Hey! I think it would be great if more people updated their location. This way, people would know if someone were from their general geographic area, and maybe even become workout buddies!
To update your location, click on "Quick Links" (or "User CP"), then click on "Edit Your Details". Toward the bottom of this page, in the "Additional Information" section, there is an option for "Location - Where you live". Put your city/state and save the changes. Your location will appear under your username to the left of each forum post you make.
