If you're interested in listing your location,

There doesn't seem to be a way to note your city and state on your profile other than to go to "My Profile", then click on "Account" then scroll down to "Signature". You can put anything you like in there, including your real name and hometown. Your signature will automatically appear on every topic you post. See mine below.

Several years ago, I made a worldwide map of our members. That was helpful but it became time-consuming to keep it updated with everything else that popped up. If someone else would like to start a new one, I'd be happy to help them.
