Well, ordinarily, that'd be a bad idea; too easy to spread virus's around.
However, the ff7 modding community is fairly closly knit (pretty much this site, and gamevn or something like that, and i -guess- animevamp), and i don't think too many people would bother uploading a virus that'd only affect like, 100 people at most, as most people who even HAVE ff7 pc are unaware of patches and mods for it..
I think perhaps at least a signup option should be in order so you can track who uploads what. Just for precautions sake.
