<I>If you have a WordPress cookie set in your web browser, anyone using your computer can access the Adminstration Panels of your blog. If you don't want this to happen (perhaps you are using a public computer or a computer which other people use), you can click this Logout link, and WordPress will delete the cookie from your web browser. </I>
I have two different user names.
I can't logout and log into my other user name. I clicked the logout button in the Dashboard and it just does not work.
