Maybe I'm the only one who wants to see just characters stages and music -- and I'm pretty sure everyone hates to see music uploads (I have no idea why. Probably the "it's easy so it sucks" mentailty, but it's not THAT easy unless you had a program that did everything for you -- the song, the looping, and the calculating of the samples)
While I have to agree with most of these ideas, they're probably hard to implement if not outright impossible to do so for the mods/admins.
The 0/10 rating system would be flawed, since, unless noobs did not have permission to vote, it would be a buttload of 0s and 10s to vote instead with a rare occourence of 5s. Essentially you'd be getting the Youtube Like/dislike function but with more space being taken.
