I suggested this a little while ago but no one seemed to take any notice of it, I personally think it's a great idea, and if you browse forums belonging to the big name servers, they all have one too

I think the reason they haven't done it is because of troubles with the chatbox they have at the moment, I may be wrong but I believe they are still sorting something out with the VPS company regarding the chatbox on the forums homepage that is always unavailable.
