Oh, and one more quick thing. Sorry!

Code:
on *:text:!join:#: { 
  if (%listopen) {
    if ($read(list.txt,nw,$nick)) { msg $chan $nick , you're already on the list silly goose! | return }
    elseif (!$read(list.txt,nw,$nick)) {
      write list.txt $nick 
      msg $chan /me grabs her pencil and adds $nick to the list
    }
  }
}


What should I add to this to make it so that if someone tries to join and the list is closed, the bot will say "Sorry, but the list is currently closed"
