I am in the habit of properly logging off my online connections. Where can I do that here on superuser.com?

To adhere to the quality standards of this site, I will not describe what I have already tried:

• I have tried to look for a sign-off link
• I have tried to look for a sign-out link
• I have tried to look within my account for a link to sign-off, sign-out, log-off or log-out.
