For new subscribers to the channel, Try the following:

Code:
on *:text:*:#coldsidetv: {
  if ( $chan == #coldsidetv && $nick == twitchnotify && *just subscribed!* iswm $1-) {
    $msg #coldsidetv $$1 has just subscribed to coldsidetv! 
  }
}


I see that you give some kind of Bonus to the person subscribing. Thus try this:

Code:
on *:text:*:#coldsidetv: {
  if ( $chan == #coldsidetv && $nick == twitchnotify && *just subscribed!* iswm $1-) {
    $msg #coldsidetv $$1 has just subscribed to coldsidetv!
    $msg #coldsidetv !bonus $$1 1000
  }
}


As you can see, I've added another $msg line to it. This will give the chat another message thus probably giving the subscriber in question the Bonus of 1000 something eek
