Well, unless you only want to meet people from your conference anyhow, you may want to post city and date as well, as there always may be forumites around who would be interested in joining a meetup.
AAC&U is a secret code not everyone understands. If that's the purpose, that's fine, of course.
Good points. I just figured, if you were going, you'd know, but I understand about people who are already there. (I've worked in four places where people were
not already there, and so I don't think about the fact that in some places nonconferees might actually be in residence.)
