This is one I may need to hire someone for but here's the idea, I would like to have a forum where people can challenge eachother to a guitar battle. The the public can vote for a predetermined amount of time at which time a winner is delcared and awarded somehow, maybe like scroungr's game hack award. Just thinking out loud here, it would be a nice addition to my site and a lot of potential uses

The "Challenge" part is already built into scroungr's game addon - you could probably glean it from there.

How they would actually battle I am not sure (attached .wmv file?)...but that is up to you!
