I don't know if anybody has heard of this IM (yes, another IM to dl to your PC), but this one is pretty cool. It shows what your Friends are playing, and if they are playing online game that you are able to jump into, there is an icon that you can click that send you straight to their game.
IMO, it's a lot easier to do that, then say remembering the Server # of the game they are playing.
If anybody dl this, tell me what they think of it.
