I have been logged onto several multi-user computers and need to make sure I am logged
off all of them. I have been careful but I went to the home page and got a login prompt like I
was logged off, then went to forums and was still logged in. I need to insure I am logged off everything.
Thanks in advance.

You could always just change your password. Other than that though, you'd need to log off of every computer.
