How do I log out?

Hello.

I have installed drupal 7.8, I have configured it as admin; I also created a new account for me, as a normal user.

I logged out as admin, logged in as normal user, but I can't log out, as there isn't a « logout » tag anywhere on the page... This is with the Corolla theme.

So how can I log out, and how can I put a « logout » tag on the pages for my users?

Thanks.
