[auto]

This is what i have in my .htaccess in the root directory:

RewriteEngine on
RewriteRule ^vbulletin/f([0-9]+)/s([^/]*)/$ /forumdisplay.php?forumid=$1&s=$2 [L]
RewriteRule ^vbulletin/t([0-9]+)/s([^/]*)/thread\.html$ /showthread.php?threadid=$1&s=$2 [L]
RewriteRule ^vbulletin/[ft]([0-9]+)/s([^/]*)/(.+)$ /$3 [L]

and the rule does not appear to work

My vB is here: http://www.automotiveforums.com/vbulletin/index.php

any help would be appreciated.
