Interactive Web Applications used to build forms for websites, blogs or emails.

I believe a good interactive Web application would be some type of form builder so we can add forms to our websites and emails. One site I found is Email Me Form
which is completely free and helps you create forms for your websites and emails with out writing a single line of code.

Wufoo Tour Builder wufoo.com offers a drag and drop option to create forms for emails and websites you can even get the files from Wufoo to manage yourself for seamless integration with your website. They also offer different themes where you can change the colors, logo and topography of your forms to match your brand or style.
