It really is frustrating trying to ask some1 to play a game and all you get is "his or her privaty settings prevent your message from getting through" This and the fact that the messenger doesn't show on the windows bar, but on the room page, is annoying...

You have 3 options: just sit and play any1 (and you will probably leave even more frustrated);or start asking people on lobby to play or to turn their messenger on (that i hate); or just go play somewhere else...

Just my thoughts
