The story
It began as a communication tool for the "Foro 50 años bastan", a meeting against the IMF and World Bank celebration in Madrid in 1994, which was promoted by the NGO Sodepaz. The tool received technical support from Alberto J. Jiménez of BBS Revolware and Russell Gasser.
At the time, Nodo50 was running the Waffle software on the DESQview multitasking platform. It exchanged emails with the GreenNet server in London using the UUCP protocol via a hacked Telnet connection. At the same time, the IPANEX association was the co-ordinator of similar projects on the continent. In 1996, with European funding from the EPITELIO project, it made the leap to the Internet through InfoVía. Since then, it has been working on a variety of campaigns, actions, projects and congresses, together with a variety of social movements and political organisations.
