Sometimes there is a need for more than 2 persons to talk in the same channel (for instance when swapping 3-player lootspots, or doing some complicated trade, or you just want to settle something without conforming to PEGI-7 standards). Regular 1-on-1 whisper is not an option. Also, hijacking some low traffic channel is discouraged by admins. Current proper way is to ask a mod for a channel, and eventually you'd be provided by one, but you'd still have to conform to PEGI-7, and you're cut off from global-1 (or whichever global-X you're usually on).

I propose a new feature, lets call it "group whisper". New command is required that would automatically allocate new virtual user named, for instance, private-X, where X is some number. Maybe just "/w private" would do, and server would allocate the channel and great anyone who enters with "welcome to private-X". So, first user opens a new whisper channel and sends the channels name to all other users. All other users can join in with normal command "/w private-X". And that's it. When all users leave new channel the channel is deallocated.

Care should be taken about privacy, so that no one can just sneak in whisper unnoticed and stalk there. Maybe this could be solved with a notification about entering/leaving the channel, like in proper IRC chat rooms.
