In register.php, replace this:

        $url = str_replace("\"", "", $url);
        if (!$url) {
          $url = "index.php?s=$session[sessionhash]";
        }
        eval("standardredirect(\"".gettemplate("redirect_registerthanks")."\",\"".iif(strpos($url,"register")>0,"index.php?s=$session[sessionhash]",$url)."\");");

with this:

        $url = "http://www.outside.com/site";
        eval("standardredirect(\"".gettemplate("redirect_registerthanks")."\",\"$url\");");
