I have heard of it, but not used it personally. I note there is a free demo available at the company website

I don't have time tonight to explore this product - perhaps someone else can tell us whether it is a worthwhile purchase.
I'm always in favor of avoiding reinventing the wheel every time I want to take a journey. I've created a lot of forms in the past (for filling out via computer by just filling in each blank as it pops up on the screen.)
My interest in such a program would be if the data entered in a form were easily or automatically copied to a central database for tracking and audit purposes and for collaborative purposes with colleagues, suppliers, and customers.
