The forum attracts a lot of ads from women who primarily live and work in Dallas. Some qualify for posting ads here by saying they'll do outcalls to Fort Worth (though they may not mention it in their ads); others just post there in the hopes that Fort Worth guy will drive to Dallas to see them.
The point is, it benefits you and your potential clients to specify in your subject line that you're actually in Fort Worth. That way, potential clients know whether you're geographically compatible, and you don't have to waste time with responses from people who aren't.
