Building a site that offers services?

Dear Pascal, how are you? I’m from Argentina and I have a question for you regarding Webiva. Here goes:)

Our software development team created a game “Prodebook” with Ruby on Rails / PostgreSQL. Since its inception in 2010, the game is on Facebook (apps.facebook.com / prodebook), but now moved most of it in a website based on Joomla CMS (used in other projects and running PHP / MySQL); the portal is www.prodebook.com.

For this reason, I am looking for a CMS to unify the users of my application and methods of access to Facebook, Twitter, Orkut, etc. with all the facilities to create a community.

We want to build a community of football fans throughout the game that allows us to fulfill our business strategy. Webdiva could be used for that purpose?

Thanks for your attention and congratulations for the application!
