It would be mostly a chance for us to catch up in person as opposed to on LJ, but also to revive some of the traditional fun like Slash-Off writing contests and suchlike. And of course to dress up (if you want).
Who likes the idea?
Who has any thoughts about potential venues?
Who has a different date they would prefer? (This is why I'm suggesting it so far in advance, though, since hopefully people's calendars aren't that full.)
