e-Socrates aims to create "the best free Moodle hosting service for everyone who wants to do e-learning activities".
You can create a course and "have the full moodle power in your hands, without restrictions of any kind!" including being able to track your students subscriptions and setting a password for the course enrolment.
In order to use the site you must "always allow website visitors the right to read your contents, you can prevent them from subscribing as students but you can't prevent them from accessing the material".
This is the only "fee" required by e-Socrates in exchange for the free hosting service.
Currently there are over 500 courses available in different languages including Bulgarian, Catalan, Czech, German, Greek, English, Spanish, Croatian, French, Italian, Polish, Portuguese, Russian, Vietnamese and Sanskrit.
Lots of sharing going on here :)
