Private messaging question

[paidtoshop]

Hi

Does anybody know how I can set up a PM group, a bit like you would do in email a list of people associated to a group name.
The reason I ask is I have over 10 Mods, and some other users that help out on the site. Sometimes I just want to send a PM to them all, but to do this I have to keep adding each user to the list.

Any ideas, any mod out there that will do this now??

Thanks in advance to anybody that can answer this
