Just one thing to add to what Smokey said:

If someone takes an issue to PM, and you have an issue with it, take it up with the Mayor. DO NOT take the PM public.

If you have an issue with a poster, discuss it with the mayor. No need for publicly calling someone a troll. It does no good, it just creates conflict.

If you feel the need to question the veracity of a post, just remember, tact is a wonderful thing. (Which I sometimes lack, but I try)
