In order to add new subscribers to NXT they need to be a constituent. We're currently forced to say "donate $10 to subscribe to our newsletter" when ideally they could just sign up with they name / email, become a constituent, and be automatically added to a list of our choosing. Ideally we would be able to create a simple subscription form like other email services that would allow people to subscribe quickly and easily and we don't currently have the ability to do that.
