I am wanting to integrate the new Facebook Registration into an already existing website. I am wanting to give the user an option to sign up using facebook or to sign up manually. If you scroll down to the 'Custom Fields' section on this link you will see what I want.
[url removed, login to view]
Our fields will be different but the process is the same.
I also want to implement the Login + Registration Flows found on that same linked above page. I have attached the Facebook flowchart explaining how it works.
The website it will be installed into is highly customized featuring our own back end. I would prefer you make the changes on our dev site and then I will push them to the live site.
Experienced programmers only.
This is what I want.
Notice the Register button on form when logged into Facebook. Also notice the 'Sign in with Facebook' in sites header.
