I have added a new rule you can check it out in the Rules post it is at the bottom off the post if you do not want to just take 5 mins of your time to check out the post the rule says:
"Triple Threat/Fatal Four way rules:
1. In a Triple Threat or Fatal Four Way if a person hits a finisher on one off there opponents then the other superstar is allowed to throw him out off win and steal the win, for example: If there is a match between John Cena vs Triple H vs Randy Orton if John Cena hits the Attitude Adjustment on Randy Orton then Triple H can throw John Cena out off the ring and pin Orton."
2. You are allowed to team up in a triple threat/fatal four way match against the other opponent.
