I don't know how the admin's here feel, but I do think you should limit multiples to formats that can be used by multiple programs. What I mean is post the formats that are the most usable by all programs. 3DS, OBJ and LWO can be imported by pretty much everything that I use. The universal types are the best to post and they cut down on spam accusations. If there's a program that can't import one of those three formats and you can make a version that that program can use, then I'd say yeah add one more format for that program. Just this user's opinion.
