cause now you see they're online and go to start a game and send an invite.. not sure what they're busy doing and they might have to drop a round. If somehow it could say what they're up to, like at what stage in a round or practicing or just surfing around. Cause i bet you right now the ratio of game join invites sent doesnt work-out too well because you dont know what their playing status is. Needs to be a 3rd column in the available friends box, saying their current game status.
