We have had a difficult time getting people to fill out the OCF message board questionnaire as to where they actually are. With our forum search function you can search the 7500 members by geographic locations.

But the issue of privacy in most people's minds prevents them from even filling it out with something more than USA or UK or whatever. Some even put in things like the sunny southwest..... So while it is something that we have considered, getting people to be honest and open in their profiles with at least their city and state, isn't going to happen. Many people fear that an employer or whomever may learn something about them from their postings that might negatively impact them. Given our recent discussions about the loopholes in Facebook, that concern is unfortunately real.

While mine is set to show members by number of posts, you can just as easily sort them by geography. All this is under the user list at the top of the page
