The support for both subscribing and non-subscribing members is excellent. My application was nearly complete by the time I registered. I wanted to be absolutely certain I could accomplish my goal prior to spending any money. The team there is willing to go above and beyond to make their customers happy. Only down side to the support is that there are really only 2 people who do support. They do an excellent job but they only have so many hours in a day.
In short, if you are willing to invest some time to learn this application, it will reward you with the power to easily create powerful custom applications for your site. IF you just need some simple forms stored in a DB or emailed, it can do that quite easily too!
