The code pretty much explains it all. I want to make it so that if someone else types the command besides the specified nick it gives them a message.

Code:

on *:TEXT:hello:#: { 
  if ($nick == Coolkid661) {
    msg $chan Hello creator
    elseif ($nick != Coolkid661) {  
      msg # Hello welcome to the stream!  
    }
  }
}
