If this is still going on, I'd be interested in joining. Fairly big Naruto fan and I know a lot about the series so I won't be walking around without a clue. I've actually been looking for something like this on other RPsites. A Ninja War in the mold of something like the first three Great Wars in the series would be fantastic. 

I'd offer myself to be Co-GM, seems like you already found someone, though.
