PM All users

[Nubius]

I got the idea for this hack (and maybe it's not a new idea but I didn't find it) when I saw a hack that would automatically PM users after activation, I was wondering if it was possible to make a hack that would PM All users, somewhat like an announcement except not too many people actually look at the announcements, it would be real handy if you could actually send the PM from the admin control panel and possibly (if not too difficult) either have an option or make it default to not send to admins or moderators, I'd love feedback on the possibility of it happening or not happening, thanks
