I chaired 2 Engineering Board meetings using a Zoom equivalent and was a member of a few accreditation panels, in the lockdown period. My experience was as follows.
For the first Engineering board, I was unable to get my camera working, but all the other members had theirs on. The effect was excellent. They couldn't see me, but I they. It had a Wizard of Oz vibe, and was extremely productive. At the second ,when I had a more normal response, people were getting used to the novelty. The accreditation panels were more off screen but find. Anyway at the second Board meeting, I announced my retirement / resignation ..but it was only a meeting earlier than the structured duration. There was of course weeping and gnashing of teeth ..
