Well what you would use is in your php file for including vBs stuff is:
Code:
error_reporting(E_ALL & ~E_NOTICE);
define('NO_REGISTER_GLOBALS', 1);
define('THIS_SCRIPT', 'pagename');
require_once('./global.php');
Change pagename to you file name.
Thats it simply, if you want any more help (For getting vB posts on a non vb page) just ask and i'll write you a script.
