If I click on General forms I find a public link where people can register for my newsletter. I do not want that such a link exists. How can I disable it?
Explanation: I have a membership site and I send a newsletter to those members with MailChimp. I synchronize the email accounts from MailChimp with the database of my membership site through https://github.com/drewm/mailchimp-api/ and webhooks. I only want that people from the membership site are included in the newsletter.
