One more thing I'd suggest looking at your site. I would have a "sign up now" button on every page with the big picture of the girls. For instance on this page:
http://www.tijuana-whores.com/brothe...icago-club.htm
That way they have one less hoop to jump through to join. Put a signup now button on every one of those big images pages.
Also these pages have some broken links:
http://tijuana-whores.com/brothels/t...-sex-tours.htm
http://tijuana-whores.com/brothels/tijuana-red-zone.htm (at the bottom, back to main)
