I don't think I have any re-directs working after the splash page before you get to the forum. Here are the url's filled out in config-int:
// We need to know the server paths to both your
vB installation and your PhotoPost installation
$vbpath = "/home/httpd/karicream/houstontexasswingers.com/html/vbulletin";
$pppath = "/home/httpd/karicream/houstontexasswingers.com/html/photopost";
// We need the URL path to your PhotoPost and
vb installation
$url_path = "www.houstontexasswingers.com/photopost";
$vb_urlpath = "www.houstontexasswingers.com/vbulletin";
