I participated to OWASP Italy back in March. OWASP Italy was a success story: more than 200 attendees, 9 great speakers, 5 sponsors, 1 round table and an article (in Italian) here:
Here is the OWASP page of the event in English with the presentations:
It was very nice to meet Matteo Meucci, Stefano Di Paola, Giorgio Fedon and Jacob West in Rome. The organization of the conference was fantastic and good lesson for me. Wish one day I will be able to organize a similar event with my OWASP chapter here in USA. My kudos to Matteo bellissimo lavoro, bravi!! Go OWASP!
