Some people have asked for it, just a chat you can chat in live instead of posting on threads. I personally do not care for it but if some of you want to use it, have at it.
I can see it being good during a challenge if I want to give instructions and not mess with a thread people keep posting in or it can be good for some challenges. Test it out see if it lags, etc for you so we can see if we can use it later. You have to click on the thing that says log in in the corner of it.
