We’ve Got DOI-s!

At long last we’re official, and the GCMAS 2021 conference proceedings have DOIs attached. You can find the official proceedings here or else use the DOI:

If you’re not familiar with these, digital object identifiers (DOIs) are intended to provide a “permanent” link to a resource such as an article, abstract, or even work of art. What this means is that organizations that get their own DOI prefix (ours is 10.52141) commit to taking the responsibility for maintaining resource links in perpetuity. Right now, these resources live on

What does this mean for you? It means that now you will finally be able to start citing GCMAS abstracts in publications via their DOI. DOIs make documents easier to find as they are stable regardless of the location of the resource. In academia, many of us are asked to provide DOIs of our work to “prove” that the work was published. This can be big if you are going for promotion.

When CrossRef accepts an organization as a member, they also ask that that organization use DOIs in all modern publications to help researchers more easily find cited works. Legacy works such as older conference proceedings can be grandfathered out of this requirement. What this meant for us is that for all abstracts submitted this year which did not list DOIs in their references, these DOIs or some type of URL had to be found before the conference proceedings could be listed officially. In some cases finding these were trivial, but in others where the references were by first author, year, and journal, sometimes this was labor intensive. In any event, that’s now done for 2021. I’m now going to try to do the same for the 2020 unconference as I have time. With luck those proceedings will have DOIs in the not too distant future.

One more thing – both the proceedings as a whole AND each individual abstract has a unique DOI. You should go to to find your paper and note the assigned DOI in the event you want to include them in your CVs and other documents.

All the best!

Watching Videos Post-Conference

So GCMAS2021 is over at last, but you’re back because you need to find a session video. The first step is to login. Remember that WordPress is fairly aggressive with enforcing password changes, so if you haven’t logged in for a while, you may be asked to change your password. Also, if you need a password reset, it seems that institutions that use SafeLinks may have problems getting reset emails. Email me if you have any issues, and we’ll get you in.

The screencast below shows you where to find everything and explains some of the site design changes post-conference. In short, you will go to the new “Recordings” tab and look for video icons at the top of the session information to the right. Clicking on that icon will take you to the recording of the video for that podium session.

What if the video isn’t there yet?

Videos take a bit of time for online systems to optimize for playing even after editing done before uploading, so if everything is not up and available immediately, please understand that it takes time.

In any event, thank you all for a great conference, and I hope to see you somewhere in person BEFORE next year.

All the best,

Tim Niiler

How Many Websites Are There?

One of the elephants in the room is why there seem to be a growing number of GCMAS related websites. The short answer is that we needed a flexible platform for an online conference which our other prior websites could not give us. For a slightly longer answer as well as information about logins, see this video.

Tutorial 4 – Interacting with the Surveys

Conference Participants,

We are looking forward to presenting Tutorial 4 on Interpreter Consistency on June 9 from 3.40-5.10pm. The tutorial will rely heavily on an interactive component to demonstrate the interpretation consistency of the group and wanted you to be aware what is necessary so you may prepare.

It will be best to have your phone, iPad, or tablet with a QR code reader available for use with the technology. This is an optimal option to keep your computer screen dedicated to the zoom presentation & material. A link will also be available for use on a PC. This will open a separate window with the interactive form. The information needed to complete the interactive form will be within the Zoom presentation, not within the window that contains the interactive form. If you choose to use the link option two monitors would be the best, otherwise you can toggle between windows.

We thank you in advance for attending the tutorial. We hope to see you in-person soon.

Tutorial 4 team,

Andy Georgiadis

Important Reminders!

The conference is just around the corner, so we wanted to remind you of a few things to help you get the most of your conference experience.

First and foremost, due to the nature of the conference, we highly recommend using a laptop or desktop to access the site so that you can view details of presentations.  This is not to say that you can’t access it on cell phone – only you will have fewer options with Zoom, and you may encounter certain limitations.

Next on the list is that you will need to login to using the email you used for registration and the password sent to you.  If you have already logged in, then you will have changed your password, and you will be able to navigate the site with enhanced privileges.  Note that this is an independent website from either OpenConf or and does not support Single Sign On (SSO).  If for some reason you can’t get in, please email me directly by Monday at 4pm so that we can get you sorted.

Once you have logged in, you will want to go to the “Meeting Rooms” tab.  If you’re an author you may see some additional options, but the page will essentially look like this:

The meeting buttons

All buttons on this page will take you to what looks like an identical meeting room, but the Zoom Room buttons in each link to different meeting instances.   So if you clicked on the Monday button, you would see this by default:

The Zoom Room buttons!

Since the only scheduled event for Monday is the Student Mixer at 6pm EDT, only the “Zoom Room 2” button will work for Monday.  You can always use the large left and right arrows to scroll through the schedule without going back to the “Meeting Rooms” tab, but the Zoom Room links won’t change – only the schedule display.  If you leave yourself here overnight and come back the next day – you would still go to the Monday Zoom Rooms which would now be empty.  Instead, go back to the “Meeting Rooms” tab and choose the Tuesday button.  In short – each day’s rooms have their own independent links.  [Also, note that all times are shown as EDT which is Universal Time Coordinated (UTC) – 4 hours].

Clicking on a Zoom Room button should open up Zoom from your browser and take you where you want to go. 

A common question I have received over the past couple weeks has been: what if I want to be in two rooms simultaneously?

If your default Zoom account supports more than one meeting simultaneously (because you have personally bought this support, or your institution supports this), you will be able to open more than one Zoom sessions at once.  Otherwise, if you wish to see what’s going on in Zoom Room 1 while meeting with people in Zoom Room 2, you will need to open each from different devices. 

On Tuesday and Wednesday, the schedule will feel more interactive.  Here’s an example.  If you’ve clicked on Tuesday’s Zoom Room, and then clicked on Poster Session 1, you’ll see this:

Detailed view of schedule for poster session

So clicking on a cell in the general schedule at left will show you the specific papers or content related to the cell you clicked.  For Poster Session 1, you will then see the posters by number that are available and you will be able to access 1) the submitted abstract by clicking on the green title text, 2) the 3 minute video introducing the poster by clicking on “View Video” and 3) the PDF that goes with the video by clicking on “View Presentation”.

If you are looking at podium presentations, you will only have access to the abstracts.  The other indicators were for authors who wished to know if their work was accessible by our tech team.

Detailed view of schedule for podium session

You will also note that all sessions have two icons at the top.  The first is a link to the forum that goes with the session.  Clicking on this will take you there.  You can post questions (do it by paper number to help authors find relevant posts), and if you click subscribe, you will then be notified via email of any responses.  Although you can ask questions during the meeting, it is possible that you think of something later and want to follow up asynchronously.  Note that when the full session video is available, a third icon will show up at the top by the other two, and you will be able to watch the videos after the fact.

Zoom Room 1 will be in Webinar format.  This means that unless you are a panelist (meaning speaker or moderator), you will not be visible to others.  You can use the chat functionality to communicate with others on the side (including private chat) or the Q&A functionality to post questions to the speaker.  One of the session moderators will be monitoring the Q&A (located with other Zoom controls at the bottom of your screen) for questions, especially upvoted questions.   If a moderator selects a question, Natalie may promote you to a panelist, or may “give you the microphone” so that you can followup more easily.

Zoom Room 2 will be in Meeting format and you can find out quite a lot about how the poster sessions will run by following this link:

We’ll briefly go over all of this at the start of the meeting, and some summary videos and posts will appear on the website in the next 24 hours before the conference. 

Finally, there are some best practices that should be considered if you are a presenter who is screen sharing:

0) If you are screensharing and presenting yourself, we hope that you have come to a training over the last couple of weeks.  Please confirm with us your intentions in this regards so that Natalie our Zoom tech can keep things running smoothly. 

1) Update your Zoom to the most recent version before the meeting:  see this:

2) Close all other non-essential windows on your computer.  These run the risk of being shared by accident, and may cause you to take longer to find the window you wish to share.

3) Close non-essential tabs in the browser, especially any which have media playing.  These will eat up your computer’s CPU and possibly lead to slow downs.  Additionally, media tabs have the potential to block the microphone or camera if you need them.

4) Get a hard-wired connection if at all possible.  While most of us are on Wifi, it is still not as reliable as plugging a network cable into your laptop.

5) If at home, be the sole network user at the time.  Other people should not be using high bandwidth applications such as Zoom while you are presenting.

6) Use a headset if possible.  This can help cancel out extraneous noise, but also means that your microphone’s audio quality will be better.

7) Consider your background. Try not to choose anything too distracting if you are using a Zoom filter, and if not, plain walls (green or blue) work the best.

8) Have your presentation queued up and ready to go before the next speaker finishes.

9) Don’t be afraid to text Natalie or the moderator using the private chat if you have questions ahead of time.

If you are NOT presenting and have any questions, please direct your questions to me ( or Chris Church, our program chair (

We’re excited that this meeting is finally happening after a year of delay and look forward to seeing you shortly!
All the best,

Poster Sessions and Zoom Room 2

There have been a lot of questions about Zoom Room 2 and how the posters sessions will run. This video will (hopefully) answer these questions and get you oriented

Note that posters (pdfs) and 3 minute video presentations of those posters are available for you to review right now from our “Program” or “Meeting Room” tabs. However you must be logged in to to view these. [Note this is not the same login as for OpenConf or – there is no single sign on.]

During the 1st 30 minutes of the official poster sessions (Tuesday June 8 10:05am-11:35am and Wednesday June 9th 3:40pm-5:10pm) poster authors assigned to those sessions have been asked to be available to discuss their work with you in breakout rooms in Zoom Room #2 (found in “Meeting Rooms” Tab).  They can stay later, of course, but if you’d like to interact “live” that’s the time to do it. If you have other asynchronous questions, please use the forums either by starting at the “Forum” tab, or go to the Meeting Rooms and click on the poster session. Then click on the golden forum icon (shown below)

at the head of the list of posters and you will be taken directly to the forum of interest. Don’t forget to list the poster number in question to ensure that the authors see your post and click “Subscribe” to the forum if you’d like an email alert about a response.

Poster presenters should show up at Zoom Room 2 on the day and time (remember Eastern Daylight Time is UTC – 4.00 hours) of the start of the session and let our Zoom technician, Samantha know which room you should be in.

Note that you can also come here anytime during the conference to visit Vendor/Exhibitors and to just meet with colleagues for a quiet chat. Just come to the room, and ask Sam to assign you to a free breakout room.

Let us know if you have any additional questions about posters!

All the best,

Chris Church (Program Chair)

Some Web Site UpDates

A few folks were having technical issues over the weekend due to the updating of user roles colliding with when they were accessing the site. We’re at a point where we are starting to implement visibility of content, and as such we have users who have different needs and permissions using the site. These include authors, conference attendees (added over the weekend starting Saturday), the casual viewer who has not logged in, administrators, and so on. There is often overlap in these users and what pages they should see. As of this morning (Monday, May 17) if you are logged in and have registered for the conference, when you are on the Program page you should see clickable abstracts.

If you are not logged in, the list should still appear, but without the links to the PDFs.

As poster authors are able to get their supporting files uploaded (4-page PDF posters and the MP4 video pitches), additional links will appear on this page so that people can start previewing these materials ahead of the conference.

In the meantime – I will post here when a major servicing of permissions happens again.

Finally – if you are registering for the conference, because the registration database must be updated manually at this time – you should see a login email within 24 hours of your registration. If not, please contact me and we’ll make sure you can get in.

All the best,

Tim N
