Just an FYI, there are several ways to get to the chat:
1) (the easiest way) is to access it right from the site menu.
2) It's in the center pane of the home page
3) If you click the "Main Room" bar at the bottom of the screen, it to pop open the chat window. There is another double square icon in the top right of the pop-up chat window to pop it out so you can keep it open and chat while you surf around.
