The last Seminar this summer was in Frankfurt, Germany on 25th+26th of June 2010. See for details: Schedule English Seminars
As I have had more the 1000 participants to my Seminars since May 2008, I have decided celebrate this and give a way a new Apple IPad on the Frankfurt Seminar (25th+26th of June 2010). Frankfurt attracted has 40 participants and the iPad was won by Paolo Arfani from Saipem.
