title: One-click Registration - am I missing something here?
body: <p>I'm trying to implement a 'one-click' Facebook registration process on my site. I'm getting extremely wound up because on other sites with what I want, they just have a 'Register with FB' button which they click and they're instantly given an account.</p>
  
  <p>But if I go to the FB documentation for Registration its talking about displaying an entire form in an iframe with values prefilled (which none of the other websites seem to need?).</p>
  
  <p>I have a FB Login button, which gave me a popup dialog asking to auth permissions and then I added a registration-url to send them to my registration page if they don't have an account (not sure how FB knows this? I guess it means not authorised?). So then how do I authorise the app with one click on the registration page?</p>
  
  <p>All I want to do is initiate a request on my server to make the registration using the FB user's email and user_id. I can store these in MySQL.</p>
  
  <p>Click Register > Authorise app. Whenever you want to log into the system you just click Login (saving you entering an email and password for registering and logging in).</p>
  
  <p>Am I missing something? I can't seem to see this anywhere?</p>
  
  <p>I can't understand what I'm missing here.</p>
