Moodle?

I'm trying to understand how to work with moodle. I've created an account on MoodleSocial. As I am running an eTwinning project called "El Babel Digital /e-Babel", I think it could be useful having a public space where we can "test" and publish our products (we want to build a sort of e-journal).
But I'm just at the beginning of the adventure ... I still have to learn a lot ...
