This free resource has been a life saver to me!  Jing lets you record up to five minutes (for a free account) of full-motion video on computer.  You can show how to complete tasks, guide a user through a website, teach someone how to access new features in your word processing program, and so on.  Completed videos can be saved locally (as SWF videos) or uploaded to Jing’s site, Facebook, or other sharing sites.  Jing is easy to use, powerful, and a sure friend to any educational technology specialist!
