Full-time staffers for AX2002 moderate both of 
these forums, which should be able to accomodate 
any questions you wish to ask:

http://groups.yahoo.com/group/animeexpo/

http://pub88.ezboard.com/banimeexpo

And you can catch any official announcements on 
the main homepage:

http://www.anime-expo.org/index2.html

I hope this information is helpful.
