As a researcher and activist in SolidarityEconomy (economy from a human standing point), I am a heavy user of free software. I am member of the [[http://www.socioeco.org | Workgroup on Solidarity Socio-Economy]]. I contribute on a regular (though not to frequent) basis to Wikipedia in French, and to [[http://www.thetransitioner.org | The transitioner]], a site on collective intelligence. I am eager to experiment Wikka Wiki.
