Jing

Download the Jing software from TechSmith and you'll be able to share (and annotate) sreen shots and share them with others. You can also capture short videos (under 5 minutes)and share them without having to upload them somewhere else first. It's great if I want to show someone how to do something online. I start Jing, do my thing and narrate what I'm doing as I do it. Slick!
