Not a question for me if I have them or not. More a question of do I ever switch them on....
Well the only way I do that is if someone needs to talk to me badly and quicker than in PM. Even then they have to leave me a PM asking me to turn it on or when to turn it on. Even then I might be to busy to do that.
Oh and a member will list them and a little icon is below there avatar to the left.
