Jing
Jing is a free web 2.0 screencasting tool. If you want to create a tutorial showing people what you are doing on the computer screen, this is a good tool for that purpose. It records everything that happens on your screen while recording your voice. You may need to purchase an external microphone if your computer microphone is not adequate. You can share your screencast through a url link provided by Jing.
