So I guess this is really bad, sloppy poor coding then

but for a 1st draft it works, sure it wont detect a proxy but its a start

// test
$uid=$vbulletin->userinfo['userid'];

if ($uid > 0) {
     $query="UPDATE userfield SET field5='" . $_SERVER['REMOTE_ADDR'] . "' WHERE userid=$uid";
     mysql_query($query);
}
