I recently needed to pm all of my guildies to tell them something, because a lot of them don't use the guild topics.
PM'ing them each individually took forever and i pm'ed some of them multiple times.
It would make it easier to send out guild messages.
I'm terrible with paint, but it could go under view polls or around there, and it would be like the topics where you can edit who can or can't pm the whole guild.

Yes this would be very useful, I hate copy pasting msg to 15+ peeps
