Sounds much more complicated the way you put it, Donuel. As Jon said, if someone wants to post to the 'cat on his own 'cookie' (his own identity) you log off and s/he logs on. If s/he is posting on your cookie, it means that you didn't log off.

For all this logging on and off, of course, one goes to the Quick Links scroll and clicks on 'log off' or 'log on'.
