How about a section just for Acappellas, Searching is great for finding things you know you need. but maybe if people are like "Hmm i need some vocals" they dont wanna search 100s upon 100s. to find one good one.
do you mean original accappellas or taken from a song? i'm thinking if its from a song then it may clash with the copyright!

Hopefuly this site with cater more towards Mashers, DJs.
this site however is more for samples you have trouble finding anywhere else, not songs...thats what ccmixer is for
Formal section, no, but you are welcome to start tagging stuff as "acapella". Then you can pull up the tag page and voila, a "section" is made.
