As far as I know you need to create a Facebook app, with a canvas and host the canvas content (the form) in your site and probably HTTPS is now required by facebook.
Ok. That’s great to know. We’re working on an SSL certificate once we establish which host will be using (currently switching the site between two).
So then, is it possible to purchase the premium subscription, and utilize the “sign up with facebook” button hosted on our site but done the way you outlined above so that it appears on the facebook page/site?
I also want to put a button on my FB page to have people sign up for my newsletter but I am not as advanced as you guys at the answer Stefano gave mans nothing to me. Can you dumb it down a bit please
