Our first pass at this will just be private messages between two people in the chat. Nobody else will be able to see the messages except the two people involved -- otherwise, it wouldn't really be private. :) We'll add a "mute" function at the same time, which you can use if someone is bothering you and you don't want to get PM's from them anymore.

These won't be full-on private chat rooms for a group of people. That's a possible feature for later on; right now we're just working on person-to-person PM.
