I can't seem to find anything on this at all and it's very important.
I have an annoying looney that keeps coming back and sends PMs to me and others all while not having yet confirmed an existing email address. Is there a way that i'm overlooking to stop people from using the PM system unless they are registered, (not awaiting email conf.).???
What am I supposed to edit though? There doesn't seem to be an option to not let any particular group use it. I would think there must be but I never found this which is why i came here. I ended up disabling messaging all together for a few days until the pest went away, but now I want to not let it happen again.
