Login with Facebook from Easydiscuss, Komento etc.

I would like to deploy the "Login with Facebook" button from Easysocial in other areas of the site.

For example, I am using JReviews, Easyblog with Komento and Easydiscuss. On all of these pages, you need to login to be able to submit a review, post a comment or start or reply to a discussion.

Currently if you don't have a login, the only option is to go to the community/registration page and register. This page doesn't give you the option to login or register using facebook which I think it should.

For an example of what I would like to do, see the attachment showing the easydiscuss page, the login with FB button and where I think it should be placed.

Any advice as to how I could achieve this? I would also like to add it to Komento on easyblog article pages and JReviews detail pages (which are com_content). Currently it's only available from the menu dropdown padlock or the community page which a lot of users don't find so in effect it appears that login with FB is not even an option.

Thanks for your help.
