Like others have said it's a bit confusing to figure out what it does right away. I think a demo video might be in your best interest. I read this and it was kinda helpful: http://blog.procasts.co.uk/2009/03/why-screencast-if-a-pictu...

You could use Camtasia: http://www.techsmith.com/camtasia.asp I tried out ScreenToaster as it was free and it works pretty good: http://www.screentoaster.com/

I see you don't have an FAQ page. May I humbly suggest my FAQ script side project: http://breezyfaq.com
