actually, with nickserv going on netsplits and coming back asking you to identify, you might try this instead:
Code:
on *:notice:This nickname is owned by someone else.*:*: {
  if ($nick != NickServ) { return }
 .msg nickserv identify <password>
}

on *:notice:This nickname is registered and protected*:*: {
  if ($nick != NickServ) { return }
 .msg nickserv identify <password>
}


These two cover the two different nickservs I've encountered.
