I'm using CiviCRM 4.4.20 with Drupal 7.43.
I created a profile to use for newsletter sign-up. Instead of a person signing up being set to "pending" and getting an email, the person is directly signed up and no email confirmation is being sent.
One clue to the problem is that it says "Added by Admin." I would have expected it to say "Pending (by email). Note that I am logged out when running this test.
How can I get CiviCRM to set the sign-up to "pending" and receive an email with a link to confirm?
