Greetings from Italy. I'm teaching "e-Commerce Theory and Techniques" in the degree course of "Communication science" @ University of Trieste (Nort East of Italy). Since 3 years I pushing students to develop mindmaps about EC using Freemind. Great success! First phases they are not capable to groving fast context and semantics trees but after some common sessions of work, a wide number of students are able to use it not only for mapping but also better understand the deep links between the EC region of knowledge.
Many thanks Freemind team!!!
