Diggit Drupalextras

I have installed the MaiChimp module 6.x-2.4 and activated it. It appears a block called MailChimp Subscription Form: List. When I move this block to Content nothing appears. Ho do I do to integrate MailChimp with Drupal so that subscribers can add their mail addresses to my homepage and it will be passed to may MailChimp account?
