This is an experimental question.
I go to five or six gaming cons each year, and I would like a way to find out who else from this site might be attending, so I can meet people face to face. I think this would both be fun and have some promotional value. Thus, I wanted to find out if meta is a useful place for that organization.
If you're going to be at a given convention, post it as an answer. Give the basic info about the convention (location, date, maybe anything interesting about the con) and link to their Web site. If someone else is going, either edit the original answer or add a comment.
