The Zdarmanet network

What is Zdarmanet

A shared address book system where members lists of contacts set up a global people network that helps you keep in touch with old friends.

Each Zdarmanet member owns a page made up of a personal profile but also of a list of contacts with friends and of a chat room. Everyone has a few contacts so the result is a complex network of friends that you can browse as you want. The curiosity is sometimes rewarded with the discovery of an old friend who suscribed thanks to someone else.
