I see that if I configure a option under the “Preferences” tab in Newsletter “Subscription Form” it will add a checkable box under the subscription form itself that the user can opt-in or opt-out of certain types of emails by checking it or unchecking it. And there is also a checkable box in the tab in my Newsletters composition area called “who will receive it”. But what is the function of adding a “Extra Profile Fields” option? I mean it does not allow me to distinguish who will get a newsletter or not based on any of my subscribers who have chosen certain “Extra Profile Fields” options. So what is that “Extra Profile Fields” option really for?
Thanks for the great plugin!!!
