I don't know, the stuff isn't really available to everyone since it's usually overpriced PPV or bust, and much like Puro, a folder dedicated to just that will probably get minimal traffic.
Maybe we could just add MMA to the Indy and International folder? I don't think it would get much traffic on it's own, to be honest.
I think MMA would be better served being a part of the sports folder.
Maybe that will get some discussion the folder going, since technically it is a sport. :)
