"This app, as far as I can tell, comes with zero documentation or installation instructions."
It's all right in their forum, and easy to locate - there's installation instructions, Frequently Answered Questions (EXTREMELY WELL DONE), and the code itself is chock full of context help.
This is an amazing application, because it's not just forms. It's DATABASE oriented, fully customizable, and feature rich. It was also one of the few "BIG" applications that installed flawlessly and without a hitch (from a tmp folder where I had extracted it).
I'm very excited to play with this one, it's a must have!
