I don't think this is set up to support a chat room.
I am only on one chat room, and any more than a few people it tends to get outta control.
Good thing about a chat room is possible one-on-one interaction.
Bad things about Chat rooms are they pull a lot more Megabytes if you are on a plan like I am, costing extra money by sending you over your plan limit, the afore-mentioned control issues, and the madding habbit of dropping signal often when you're on wireless.
