What about WikiExpo? (though I'm not opposed to something with World in it,
a la LinuxWorld/MacWorld)
Looking at [[Conference <http://en.wikipedia.org/wiki/Conference>]], I'm
getting a few ideas, but nothing too special. I'll send something in if I
think of it.
Ooh! How about WikiSem <http://en.wikipedia.org/wiki/Seminar>, to go along
with WikiSym? Or too similar?
