Internal chat.

Create an internal chat tab with subscribers and subscribed for simple online communication.For example, I like the work of someone I am subscribed to and would like to know some details or share my opinion on how to improve or eventually work on a joint project. But for this you need direct communication. I think it would help many people to communicate and create. It would be good, useful and pleasant to visit the site to see the Chat tab, two out of five subscribers are online or you are subscribed to 10 authors three are online...
