Question
I want to create online forms similar to Wufoo, but with the ability for people to save their work and return to it -- and also for multiple forms to be linked together. I'm not technical, and I don't want to hire a programmer to create a system which I cannot change myself. Seems like there ought to be something that's one level up from Wufoo in sophistication, but not so technical that it would require specialized knowledge.
Answer
I would recommend you look at Gravity Forms which you can use on a Wordpress framework. The forms are easy to put together, and have a great deal of flexibility and options for integration with other platforms. You can easily use Gravity Forms for multiple stage forms.
