If location had its own field, it would simply be a matter of inserting an include command. If you tried now, it would include the user's location, plus everything else they put in that bio box.

I still have no idea why they didn't just make Location a seperate field. They could have had Location, Occupation, and Interest fields, then added the extra box for bio. That would solve a lot of problems with importing member files, displaying locations, searching the memberlist by location, etc.
