Facebook privacy tour offered to newbies New Facebook members are beginning to see a step-by-step privacy education tour when they sign up, part of a stepped-up campaign that addresses concerns of a European regulatory agency. [...] because the company's international division is in Dublin, Ireland, the data protection office became the watchdog agency for the 818 million Facebook users who live outside of the United States and Canada.
