This collaborative work platform for the web has for its theme the sinking of the Baltic Sea ferry the »Estonia«, where in September 1994 over 800 people died. To this day, the causes behind this tragedy have not been clearly resolved; mysterious events and contradictory investigations are always giving renewed cause for speculation. Editorially treated material is available for visitors, but there are also intelligent search engines for research within a database and on the net. With the opportunity to meet other interested parties on the platform and to be able to discuss and work on documents together with them, the platform should become the basis of a living community.
