I do not know all the CM's, but of the ones I do know, and I am pretty sure they are representitive of the group, if they did have advance knowledge that would help their side as a player, XO, CO, whatever, it would not be used, even if it ment serious trouble for their side.
This is only a game (or so my wife tells me) but I think there is enough respect for all that no individual would abuse his/her powers as CM to influence game outcome.
Personal opinion, of course, but if you let me down Jordi, I will come back east and haunt you!
I voted Yes.
