I am a new user and I am trying to figure out how I need to set up a signup page so that if a person wants to pay using a check or money order, they still get added to the system and get sent reminder notices at the end of a month for a subscription. I realize that I will probably have to manually activate them but I do want them to get the expiry notices so they know to renew but what payment system is assigned to the product? I assume I have to set up a separate product for this option and maybe assign a price group like -3 so it shows up on signup form by itself but what payment system - is there a way to show "pay by check"?
