Most sites offer such a button on every page.

Since TWiki is using HTML BasicAuth, the LogOut button would simply lead to a page which explains that you need to restart your browser, or for some browsers, that you need to kill the cached copy of your username/password. (Mozilla: Tasks > Privacy and Security > Password Manager > View Stored Passwords, find it in the list, click on Remove.)

While this may seem silly for most use, I've gotten stuck at times when I've wanted to edit pages on a TWiki that I don't frequently use. I forget my username, or that I have one. So I log in as guest, and then later realize I had a username, but it's not obvious how to start using it...

added to UsabilityIdeas since this is a frequently asked question.

One of these would have also solved MikeMannix's problem about not being able to log out between being a user doing MasterRefactor re-classifications to being a user making content changes.

Sessions using SessionPlugin or "remember remote user" also need to be catered for. Possibly by a new Plugin hook for logout.
