League Based Chat
I would like to suggest separate chats based on leagues so we can communicate with players who we will be playing against.
I am currently in 0-4 in Division 2:2 and would like to say farewell to my fellow managers before my inevitable relegation. League based chat would help in this regard. :v)
Other browser based games often have a feature of this kind, for example: the football/soccer management game Xpert Eleven has a Scribble chat to leave notes and exchange friendly banter with other players in your league. In my professional opinion as the Season 2 MVP, It makes the game a lot more fun to interact with players in this way.
