I reading the membership pro 2 directions I am led to believe that I can use Gravity Forms for my registration form. As far as I can view, the only think I have to do is add add_filter('ms_frontend_handle_registration', '__return_false'); to functions.php file.
I don't see anywhere in MP2 where I designate the form as my registration form.
I I created my registration form using gravity forms and the user registration add-on. I filled out the form and basically, the only thing that occured is that a new user was created.
So Gravity Forms, as usual, did it's party
Where does Membership Pro 2 kick in?
