Access MailChimp forms I currently have a form that it is fully loaded from my Mailchimp Account. I configured it for display as a page using mailchimp configuration page (admin/config/services/mailchimp/signup). Then when I was trying to access it with no admin permissions I got Not authorized to access this page message. 

Giving Access all Mailchimp Signup Pages permission to anonymous users fix this problem but it specify that have security implications and I think it is a wrong solution. 

I searched all the drupal interface and was not able to find it on either side (Content, contact forms, etc...). This element it's only present on signup forms list (admin/config/services/mailchimp/signup) and there isn't any permissions configuration.
Recently found a FAQ from Drupal Mailchimp módule here
It says:


  Q: How do I create anonymous signup forms on the site as either a page
  or a block?
  
  A: Head to this path admin/config/services/mailchimp/signup/add, fill out the form and
  click on “Block”, “Page”, or both Display Modes.
  
  Block - ...
  
  Page - enter a path for which you’d
  like the signup form to appear, and click “Save”. In order to make
  SignUp pages available to anonymous users, head over to where
  permissions are assigned (admin/people/permissions), and check the
  appropriate boxes next to the permission marked “Access all Mailchimp
  Signup Pages.”


So this means that I should ignore that warning.
