Once an opt in group is created it will give you the html button code to allow people to opt in. We'll try to get an updated tutorial or video to highlight how that works.
I don't see it...
I added a new "Group" then went to the users_update.php page and still see only two types of Access Groups (Admin or User)
I want to be able to have more than one list of users that get specific campaigns.
I believe you are using the term Audience as the user group. But when you add a new user via the pages available in the admin area (/admin_pm/users_registration.php) there is no option to distinguish which "Audience" they go into.
Please advise on if having multiple user groups that receive different mailings is part of the intended functionality.
