Two page Wordpress registration, with custom user fields & mailchimp api

Integrate a new registration page (this is already created in HTML/CSS format)
into Wordpress, Also with Facebook integration and browser level authentication.

A second registration page, that all users are sent to after the first page.
(Already complete in HTML/CSS, just needs implementing and custom user fields setup)

Custom user fields integrate both with Wordpress back end and MailChimp API

Each user can edit the custom fields on a my account page (not created).

A new login screen (already created in HTML/CSS) but with Facebook integration as well.

I expect this to take less than 1 day, ideally finished by Friday 23rd March.
