Hi Jesse, there are some free tools for screen capture available - one is called Wink (http://www.debugmode.com/wink/) and another one is called CamStudio (http://camstudio.org/). Those will work, they just are not quite as slick and easy/quick to use as Camtasia.

There is also a newer thing called Jing (http://www.jingproject.com/) which I think is free and also from the same people who do Camtasia so that could be another candidate.
