If you have been experiencing a white screen when opening the chat room over the last week, it may be due to some additional security features we added to the chat room recently. These features are, unfortunately, incompatible with the techniques a minority of ISPs use to attempt to optimise your browsing experience.
To access the chat room with these security features disabled, there is a link below the "Enter the Chatroom" box, called "Open with additional security features disabled". This should allow you to access the chat room.
