Everyone is allowed to have an opinion, but no one is allowed to post unsubstantiated allegations of cheating, of favoritism and other inapropirate behavior by officials such as telling you something in private and something different in public, etc. That is why your recent post was edited Matt.
If someone has a suspicion but no proof and you think we should be paying special attention, tell me in private. If someone has proof, bring it. If I'm the problem, bring it to NASA HQ. Either way this is not the place for spreading rumors or slandering someone without substantiating the claim.
