Im not sure on what to call the thread, but this is what im looking for..

I am looking to make a video tutorial on how to navigate my site, and to make it even more user friendly I want it to voice the words instead of me writing little text snipets. Since most people dont like to "read", It will be more convient to voice it.

I am aware of SitePal, but im looking for something that is free.

Also, what software should I use to record my screen? I currently use Camtasia Studio 3.

Thanks, in advance
