Talking about How to config the 'Windows Live Authentication 1.0' in the 'Community Kit for SharePoint'

The 'ReadMe' file in the project is very helpful, however, when I finished all the steps, the web page that I opened just says 'Access Denied'.  This is because you haven't configure the permission in the SharePoint yet, it's just like the relation between AD and SharePoint. You are authenticated in AD, and you also have to be authenticated in SharePoint too.

Keep this in mind, now you just go to the central admin and change the site collection admin to the Live ID that you are using, and then you could access the page with the admin rights and you could do other configuration such as add the 'Authenticated Live Users' role to the SharePoint Visitor, etc.
