Website part on CI

Hello, we need a CodeIgniter website using MVC which will later be integrated by our developers to another multilingual CI site. The site has to be like Facebook Wall and news feed but only these two simple and connected parts. The only slightly different will be that when accepting a friend request you will be assigning them to certain lists like circles but a user can be added in more than one circle. That’s all the project and a simple backend to manage users and keep record of all activity and connections.
