Author's Response:
Thanks for the tips and review.
You are right, the newgrounds system lets the author vote on their own work once. So i often will do the initial vote. The thing is, the way the audio system works, if i give something a 5 it will appear at the top of the list, more people will see it and vote on it, which moves it to it's fair place. If i leave it at 0 then people may never see it to decide what they think. It just seemed to make more sense to get it out there.
Anyway, thanks for the feedback.
