Well, your logic is right but you don't actually use the word then wink

Code:
on @1:DEOP:#:{
  if ($remove($address($opnick,1),$chr(42),$chr(33)) == ident@hostmask.com) {
    mode # +o $opnick

    if ($nick ison #) {
      mode # -o $nick
    }
  }
}


Though, I think your best bet is to make use of the userlist, especially if there are many [email]ident@hostmasks[/email] to check for.
