This is Chris Coyier from Wufoo. Looks really promising, thanks for the work! This part of the installation process doesn't seem to be working:
After clicking the button for the first time, follow the simple setup instructions to connect your Wufoo account.
Just getting this: http://cl.ly/2EyB
Also, we have a few guidelines we ask third party developers to adhere to, which is spelled out here: http://wufoo.com/docs/api/v3/third-party-application-rules/
Essentially, you can use the supplied badges, but nothing else from the site. If you have any questions, please get in touch with me at firstname.lastname@example.org
I'd love to give feedback and help promote this from our website when it's ready!
