task Integrating MailChimp API to Subscription Form

MailChimp, a mass emailing solution, offers an API so that you can use to create native, fully customized sign-up forms on a website. I'm using this API with a little PHP for a client's newsletter sign up. Of course, MailChimp also offers their basic copy-and-paste forms as well as MailChimp-hosted forms, but you can't achieve nearly as much customization as you can when you use the API.
