I have been using mailforms several times and was always happy. But if I had to create more complex forms, mailforms was simply not enough. 3 weeks ago I received the newsletter that the new version is out. I waited 2 weeks until I bought. I should have bought it on the first day of the release. This is such a grand step. It's almost like from Win95 to WinXP. The backend looks great and does have lot of web 2.0 scripts built-in. The most important improvement is the layout-extension and multiple templates. I don't need Paypal or database, but I think for others this might be also very important. For all those reasons this is my favourite form component.
