Iftah Gamzu requested that I post on the following topic. When I began to do it, I realized that his email to me, edited slightly, says it all and says it all well. So here is a guest post by Iftah Gamzu:
My name is Iftah Gamzu, and I'm a PhD student in Tel Aviv University.
Some time ago, several people brought to my attention the need for a
web page that will list past invited speakers in theory conferences.
They mentioned that such web page would help program committees, and
especially program chairs in the decision of who to invite to present
plenary talks. Consequently, I devised such web page
are still missing pieces of information that I couldn't track down on
the web. SO, if you know some of the missing info, please email
