The program is awesome. Spectacular. Your business practices are manipulative and shady. As much as I like the actual experience of using your website, the way you rope people in to pay for the privilege only AFTER they finish their documents is clearly intentional and very very suspect. For that reason I will never recommend this to anyone.

I used this program for one item in the past and just discovered today I can use it for many other types of forms such as Income Tax etc. Very easy to use, thank you. Wendell Juhl
