Just an FYI...You can block private messages | Arthritis Information

You can block people from private messaging you.

Just click on the member control panel and go to the buddy list box on the right.

There is a box on the right that says allow this member to:

Underneath is message me and not message me (pull down to get the not message me)

Once you click on not message me...add the person's screen name and their pm's will be blocked.
