yeah, we have an alpha version online, but with no functionalities.. (and without the user interface to allow content sharing)
it's a great project, but we are looking for volunteers to help on the platform..
I'm from Brazil, and the whole concept of the project is that there's no reason why a boy who lives in a slam, for example, to have no access to the same content as a boy who studies at MIT. And we want to provide a platform and means to allow that to happen through an open source and non profit platform.
