Alright for anyone that doesnt know what Xfire is, you should look it up. Its an IM device made for gaming. thats its purpose. They have really neat things with it, some helping games like call of duty 2 and unreal tournmant but also, you can make a clan/group with it. with this, assuming everyone has made a screen name with it, you can see everyone that has been added to this group. you dont have to add everyone, you only have to apply to join the group. From that point on you can see everyone that is online, wtihout having to add all of their screen names to aim. its basicly shows everyone in the group and you can talk to them easy. it works well for games i use it for.
just an idea.
