If you are not a member, feel free to browse our forum anyway. There is a ChatBox (instant messenger) at the bottom of the home screen for everyone. Here are a couple commands you can use in the chatbox:
/abs - its basically "brb" you can even list a reason for being away if you type a space and then a message (ex: /abs gotta pee)
/exit - disconnect from chatbox. like /abs, you can list a reason after the command
/me - this puts your username at the beginning of the sentence.
