Not a bad idea, I did suggest to FR last week that they put the chat underneath the categories on the right hand side of the forum (or move the Categories to the left and have the chat only on the right) and have it there permanently, but have a log in to chat button as I don't think users should be forced to appear in the chat room. At least if it's on permanent view it might encourage people to go in it.
The FootyRoom talk room was a great idea enabling us to be able to chat with each other but honesty I don't think it's very successful due to the fact no one is ever on it. I already suggested to FootyRoom that the chat should appear on either sides of the page at all times allowing all registered users to partake in conversations with any other user wether they might be watching a highlight, reading forum post or even some news or Le Mix. What do you guys think about that idea? Or maybe a different idea to get the Talk Room more active.
