If you reset your browser history or delete the entire history/or whichever way your computer operates it logs you out automatically.

Here's a hint Waterbaby shared with me a few days ago. If you don't want your history to go away, but do want your login information to go away, add the "logout" link Ray provided to your Profile. When you're ready to log out, click on your name on "Who's Around" and then click on the logout link. Problem solved. When we evolve to a more polished homepage, I figure Kandace and Ray will add this feature. In the interim, this works fine.

Here's the logout link: http://goneraw.com/logout

PS: Thanks "sis" for sharing the hint.
