Oh, as a mentor thing, opening up private posts with people you think you can trust is usually a good idea! It means you can talk and strategize outside of the wolves' sight, and it's often a good way of swaying people to your side. Look at how much good it did us here! It's especially a good idea to open up a post with the safe sheep when the third day clue is given, since they're the players you know for sure you can trust.
