seriously, it's not obvious, nor even subtle. 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.

thanks, randall
