/*   To use this example:
     1. Download this html file
     2. Replace the form action url with your own from the MailChimp supplied embed code
     3. Within the action url, replace "subscribe/post" with "subscribe/post-json"
     4. Be sure the action url starts with http://. If it doesn't, the form will hang when testing the html as a local file in your browser.
     5. Open this file in a browser on your local machine
