Embedded in the 2nd World Summit on the Knowledge Society we had a symposium that was related to the topic of Personal Learning Environments. Graham Attwell, Maria Perifanou, Cristina Costa, Ricardo Torres and me presented complementary papers talking about PLEs, Digital Identity, Contextual Learning and Communities of Practice. It was a great platform to present ideas about challenging aspect of mobile learning and the first international conference where the Widget (Messaging) Server developed by UPB could be presented in action.
