There have been some issues with logging out but even if by hitting the log out button you aren't logged out, eventually, with inactive time, it auto logs out. Its an issue that doesn't affect anyone other than those who regularly use alternate accounts as you can't log out from one to log out with the other. This said, the Admins already know about this issue and some similar ones (like those with safari which keep getting logged you (like I did)) and are trying to fix it. In the meantime, don't make more threads about it and when you have an issue, try to see if a recent thread about it has been made before making a new one.
