Session cookies are used in Mailman's
administrative interface so that you don't need to
re-authenticate with every administrative operation. This
cookie will expire automatically when you exit your browser, or
you can explicitly expire the cookie by hitting the
Logout link under Other Administrative
Activities (which you'll see once you successfully log in).
