I think you would use it the same way here that you would use it elsewhere. You need to abide by the
forum rules.
Otherwise, by way of example, I have used it for the following:
Communicating with other members regarding rules or the reason a post was removed.
I sometimes send PMs to people who find their photos here and ask for them to be removed. Usually, I am encouraging them to stay and post their women here.
I hope that helps.
