Nasza-klasa.pl, now nk.pl (nasza klasa - pl. our class) is a large Polish social networking service, bringing together students and alumni.
Launched in November 2006, the service has 13.5 million registered users. It is owned by Forticom (70%) and Polish Nasza-Klasa Sp.z.o.o. (30%), the founding company of Nasza-Klasa.
Nasza-klasa is a website similar in concept to the American Classmates, allowing its users to register from particular schools and graduation years. The users are able to keep and maintain a personal page containing information such as their name, age, photos, interests and the history of schools and classes attended. Nasza-klasa doesn't require an invitation to join, however registration is necessary to browse the service. The leader of the project is Maciej Popowicz from Wrocław.
