Crossfire Log out

In Crossfire, i think the next patch should include a logout button because it is very inconveniencing and annoying to constantly have to shut out the game to switch users. On my computer, starting Crossfire is not easy, for some onknown reason the Xtrap sometimes stops working and times out, if someone could also help me with this, that would be nice. Anyway, I'll be playing and when im done I'll let my brother play, since its the one computer that can play it, and he has to close the game and restart the long startup process that includes multiple tries until Xtrap finally goes through. So, it would be really nice if there were a Log Out button somewhere like maybe even in the options or something.
