I don't know if this has been mentioned elsewhere, I apologize if it has, but the big chat room display is blank when you go to the chat tab. The side bar displays messages, but the bar under it does not allow you to enter any messages. You have to type into the box under the main chat display, on the chat page. I've found that a few other users have also stated they have issues with this, so just thought I would throw it out there. On the home screen where there is a chat sidebar, everything works fine.
