Social Client

This idea came up to me while messing around with clubs. I noticed that it is kinda uneasy to read the Message of the Day (go to profile--clubs--the club you want--message of the day). It would be way better, in my opinion, if there was something like a social window on the client: apart from knowing the message of the day, there could be notifications for when a friend reaches a new rank (for example) or when a friend hits a new level/mastery with a chap/finds a skin ecc. What do you think about it?
