Clone the suggestion box thread nine times, rename them Movies, TV, Music, Games, Apps, Books, Anime, Adult and Other, make a landing page (or put them under a fly-out sub-menu) for requests. 

The above gets it out the door with minimum functionality (i.e. no replies or special handling for IMDB numbers, etc.), but it at least gets requests organized, might result in more re-visits to check on the request, and would result in more torrents being uploaded here.
