The aim of the present paper is to discuss the achievements and the drawbacks of the integration of LMS (learning management systems) with the cooperative tools of the Web 2.0 through the account of a supplementary online course that has taken place in an Italian secondary high school. It can be considered an innovating experience from many different viewpoints and can be regarded as an example of how the world of the formal education can meet the demands of the informal one, in the broader landscape of school learning.
