Denis, Jay, and others,
>It would be nice to know who they are. I understand that it could be a considerable task to do that right now. But could it be an alternative to do it after all the photos have been taken and posted?
After I get the last conference report done and posted and the final batch of photos selected and uploaded, I'll find some way to caption as many as I can. I can either post a message here identifying them, or I'll provide a link to a separate web page somewhere that contains the images plus captions.
So, within a day or two, you should have a way to find out who is who.
