So you've probably all seen NGU's version of renaming a user's username command in their shoutbox right? I mean who hasn't? So i took the time to make one myself for the Inferno shoutbox by x iJB x which is what NGU's shoutbox is based from. Anyway you can see the coding below, follow the instructions on how to use it etc. .

    

if(preg_match("#^(/rename\s+)(.*?[^;]);(.+?)$#i", $message, $matches) && $this->can_do_admin())

{

	$user = htmlspecialchars_uni(addslashes(trim($matches[2])));

	$selectuser = $this->vbulletin->db->query_first("SELECT * FROM " . TABLE_PREFIX . "user WHERE username='$user'");

	$checkuser = $this->vbulletin->db->query_first("SELECT * FROM " . TABLE_PREFIX . "user WHERE username='$matches[3]'");

	if($selectuser && !$checkuser)

	{

		$this->me = 1;

		$this->vbulletin->db->query("UPDATE " . TABLE_PREFIX . "user SET username='$matches[3]' WHERE username='$user'");

		$message = ' has changed the user '.$user.'\'s username to '.$matches[3].'.';

	}

	else

	{

		$this->private = $this->vbulletin->userinfo['userid'];

		$message = 'The username you have entered is invalid or already taken.';

	}

}
