Our clan uses a (free) program called x-fire to message and use voice communication with each other during games. X-fire is a far more superior instant message client than any other because it allows you to send and receive messages while you are playing your game, so there is no more need for minimizing your game just to talk to other people. X-fire also keeps a daily log of how many hours you play your games and it lets you know what server your friends are playing on, and lets you join the server they are playing on directly.

It is required, and it is highly recommended that every member in the clan have a x-fire. If you wish to download x-fire, please visit http://www.xfire.com/download/
