I'd again like to express my interest in a bounties system. Failing that, my second choice is for a User Group registry - sort of like an up-to-date version of GAUHPIL. Then I'll know where to visit when I travel!
I remember when the old file galleries were closed down due to disuse and I don't really know what benefit another file repository would have. And music mods I think are well covered by Aminet, Exotica, and the like.
