The basic idea
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 anyone can browse. The curiosity is sometimes rewarded with the discovery of an old friend who suscribed thanks to someone else.

Several mathematic and sociologic studies show that the world's population is in fact a so called small world. It means that two randomly chosen persons in the world are connected by a chain of at most 6 acquaintances.

22-03-2012: After 9 years of operations without touching the code and server, the code had to be fixed because newly php considers goto as a reserved function. Replaced with some other function name. Now you all know Facebook. I will operate Zdarmanet just for fun to show that great ideas exist but sometimes they come earlier than the right time.|
14-09-2003: Separator added to album.|
14-09-2003: "Thans to" added to contact details. In the future, there will be a nice visualisation for that.

19-11-2002: Now it is impossible to have the same message following itself in a chatroom (avoiding double-click submitions).

12-11-2002: The new homepage is launched.
