There is a pay version of the program: Screenbook Maker Pro. We've released a free version with most of the features of the Pro version so that people can create visual tutorials easily and share what they know. 

Screenbook Maker is a project of NYCircuits Inc, a New York City software consulting company specializing in XML and XSLT development.

If you are a member of large organization and would like to create a shared learning community, contact us for more information about custom community learning systems we can build using Screenbook Maker as a front end (for a bit more about this, see the next FAQ item).
