Hi I'm Jimmy I'm really interested in this feature and would like to know if it could be done.
I have a Word Press MU + Buddy Press site.
What I want is users to be able the "battle" one another. So I can go to someones album and challenge their photo or video. Example: my car is better, so I challenge a photo of your car. And if you accept the battle is created and the battle gets voted on by the community. List of specify features
Voting on the battle
All the best,
There are a couple of robust album plugins that handles the photos and all. The project could possibly be done by extending such plugins.
