In my humble opinion, IH should scrap the PM system
and tie in a 3rd party IM system, thus mooting this whole discussion and absolving IH from liabilities.
Just like anything else, it only takes a few bad apples to abuse an otherwise great tool. Current PM system could be used between users and Admin only.
Right, exactly. That's how you know it is a bad rule, because it is impossible to define appropriate exceptions.
