Private Messaging Issue
 

I have my forum set so that when someone gets enough infraction points, they get moved into a new usergroup. This usergroup is not allowed to use PMs.

The problem is that I still want the mods and supermods to be able to send PMs to these users, but not for those users to be able to send PMs to others.

Where can I do that?

As an admin, I can send a PM to the users in this special group, but I can't seem to find a way to make mods or super mods able to do that.
