Brandon - I've just activated your plug in and I think successfully integrated it with Mailchimp. I have set up a membership site using Premise, and my goal is that somebody who signs up on your widget would then have free member access without filling out another Premise check-in form. Is this possible? Perhaps by putting the product code or the [checkout-form] short code someplace? You can probably tell I'm not a coder (but not afraid to mess around with it).
It would also be useful to know if it just is not a viable goal. Thank you!
