i.Scribe is free!
Use v1.x for as long as you want no strings attached. But you can register i.Scribe (for free) which gives for the benifts of notification of software updates and new versions. I suggest you use i.Scribe for awhile, collect together some thoughts and comments and then send them in with your registration.
Future versions (v2.x and up) will probably be at least shareware or commercial software as they will have more advanced features.
