The post below I posted on the Chat thread. Honestly I'm sick of trying to communicate with people through BB-mail its a pain in the ass to have a conversation and it doesn't take much effort to either register a chat room on a server like net-gamers for Buzzerbeater and post instructions on the forums on how to set it up or to design a built in chat system. Communication is key for this game to take off especially if we join a server like net-gamers and manage to get the word of how great this game is out.
I think a chat could be very beneficial for newer players to get to ask questions and even for the more experienced players to discuss tactics and try and figure out how this game works. From games i have played in the past they have used NetGamers (http://www.netgamers.org/). On Netgamers you can register a nick and a room such as #Buzzerbeater, they provide you with a bot who only gives Ops to those the founders have given permission to so the room itself can be very secure even if non of the admins are present.
I agree a built in chat would be easier for people but I also know games such as Planetarion have a link built into their toolbar which opens a browser window using java that brings users directly to the main room maybe something like that would be possible?
