I'm trying to find a simple way to have wordpress users forced to join my opt in page if they want to register for my WordPress site. Been searching but not finding anything relevant. Right now I use S2member for membership management and it's only an option on the register page for getting my mailings. They can uncheck it if they like. I'm using mailchimp API with S2member in wordpress. Free registration is enabled. I would like it that before they can register they must opt-in to my mailchimp list. Rather than have it as an option on the register page. Even better, if they unsubscribe from the list, they should lose their WP account login access but the account should not be deleted. Is there a a plugin, paid or otherwise, that will do this exactly? Am I left having one written or moding code? What are the options? Anyone else doing this? Is it against some TOS that I have not noticed?
