Couple of things I wanted to share from Wufoo land.
Developers: We've released the Wufoo Form Embed Kit, which is a way you can build form embedding integration with other apps easily. As in, you don't have to learn our APIs or do custom design work. Would make for neat CMS plugins!
Designers: If you didn't know you could apply your own custom CSS to Wufoo forms and completely transform their appearance, you can, and here's a tutorial getting you up to speed. And did you know you can customize the look of radio buttons and checkboxes with just CSS?
