I don't thing there is away to do it at the moment as there hasn't been a demand for it. Abuse of the PM system has never been an issue on the Forum. We are ultra active on a dailly monitoring and throwing out spammers. At one point we were under heavy attack banning an average of 3 or 4 per day sometimes more per day but now we can go for much longer without any spam. If you need assistance contact us.
