How to change labels in facebook registration form?

[RIcky]

The Registration plugin allows users to easily sign up for your website with their Facebook account. The plugin is a simple iframe that you can drop into your page. When logged into Facebook, users see a form that is pre-filled with their Facebook information where appropriate.

The registration plugin gives you the flexibility to ask for additional information which is not available through the Facebook API (e.g. favorite movie). The plugin also allows users who do not have a Facebook account, or do not wish to sign up for your site using Facebook to use the same form as those who are connecting with Facebook. This eliminates the need to provide two separate login experiences.
