Rule #1: Don't be disrespectful toward a staff member unless your playing of course and its understood both ways that your playing around.
Rule #2: No Godmoding or Metagaming meaning while roleplaying don't control the other character in any way shape or form don't say he/she fell or got hit or anything. If you went to attack with your sword say you slashed with your sword don't say I hit so and so with the sword because your not giving the opponent a chance to do anything about it. Don't know things or react as if you know things when your not supposed to for ex If your opponent is behind a tree and does a clone jutsu and they split up don't know where the clone is. Or if the enemy posts something your character doesn't know respond as if you don't know because you don't...
Rule #3: Don't argue and fight with staff if you don't agree with a decision address it in a respectful manner.
Rule #4: Have fun
