Our work, under the research project "New technologies for lifelong learning and networks in the italian socio-economic system" with a number of italian universities, is directed to obtain a greater integration between the CSCL (Computer Supported Collaborative Learning) world and Moodle.
We first tried to detect the most important features required and now we are working for implementing those not already available in Moodle as additional modules (the first pieces of code are to be released very soon).
As you can read, the most significant proposals of new features are related to the forum module, so we choose to post our work in this thematic forum.

Of course, we very well welcome any comments or queries you may have!
