The two parts in red, arrange as you like smile
Code:
on !*^:quit:{
  var %i = 1
  while $comchan($nick,%i) {
    echo $v1 15 $timestamp $nick [color:red]( $+ $address $+ )[/color] <Message for quitting> [color:red]( $+ $1-)[/color]
    inc %i
  }
  haltdef
}

Same thing goes for the others as far as addresses.
Parts might have a $1- message as well.
