And now almost 5 years later is still the best form creator out there. First of i like that they got a fully working free version that i used for a couple of years until i felt i had the money to buy the unlimited version. And its not expensive.
They got a superb documentation on the website with both videos and examples.
Its not to many times i needed support but when i asked something on the forum i got answer quickly and even at times skype support. Thanks for a great extension.
