Christian Cox has created a nice tutorial (and some sample code) for building a Flash email signup form that passes subscribers to your MailChimp list. He used the MailChimp API to create some ActionScript for you.
We’d seen some examples of Flash integration w/MailChimp before, but they usually required a little PHP know-how and lacked documentation.
So a HUGE thank you goes out to Christian for all this. If you’re building websites or web apps in Flash, and want seamless email marketing integration, be sure to check this out.
