Wake up Skype to invisible from Mac sleep

One of the more annoying things about putting your Mac to sleep are the applications that you would leave up as real-time applications. Such as IM, or Skype. There’s nothing like everyone under the sun finding out that you’re back online and pinging you from the sun and back.
No sweat. Murphy Mac has a script for Sleepwatcher which will take care of that. Sleepwatcher is an open source utility that will perform certain functions on waking or sleeping of the Mac. You tell it what you want it to do and it’ll run whatever you tell it. Watch their screencast on how to do this.
