Precisely. I'm sure that someone who I a staff member would hate to be bombarded with messages from dozens and dozens of players. Even if there was a toggle feature, as suggested by
@Bob_the_Giraffe , the whole point of the friends system is for features like this. It provides a larger limit for friends allows you to /fmsg with a larger group of people globally, and therefore this provides an incentive to donate to the server to keep it running. An addition of a global /msg defeats this whole point. Of course, friends do have more features than just /fmsg, but it's a rather fundamental part of it.
