I loved the old batte.net system on Starcraft and Diablo II. Spamming /f m with random shit or only hearing half of someones conversation with a stranger was probably the most entertaining part of the game. Unless I haven't found out how yet, the only way to do that is to change your broadcast message on your friends list, but whoever is on your list with only get a momentary bleep with the message, then they'd have to go onto their friends list to view it. The chatroom function needs a little more work too. You can only invite 2 more of your friends in a channel. They also need to fix the way the RealID text appears. It looks so... jagged.

It is defnitly a great system though. I look forward to see how it develops.
