GFIS is an open-source collective intelligence system addressing the 15 global challenges identified by The Millennium Project’s 46 active nodes from around the world. The system allows subscribers to comment on any aspect of a challenge. These comments may generate discussion among users or a real-time Delphi. Newsfeeds, Web sites, videos, and books may be added to the discussions. This will allow for continuous updating of the challenges by a wider group of participants than have been previously involved. GFIS is currently in beta test.
