Skype 'wake up invisible' trick
Do you find yourself being pestered by Skype callers the minute you wake up your Mac? Yes, I know, we all should be so popular; that doesn't make it any less annoying for those who are on the world's e-speed-dial. This tip from murphymac.com allows you to automatically set your status to "Not Available" before your machine sleeps (via the SleepWatcher tool), thereby dodging the deluge of attention from your adoring public. Murphy has also provided a handy screencast showing the steps to perform.
