First steps with MongoDb & OpenId

I started my work with application that will use MongoDb as storage for OpenId creditentials and stuff. I get MVC template of OpenId application from http://www.dotnetopenauth.net/ (3.4.7). It uses mdf file database for storage. I am working now to make it Sql Server free. Project is stored on GitHub: https://github.com/robertkras/MVConMongo so feel free to fork it and add coments. When it will be working I will try to host it on AppHarbor.
