we are organizing the Foire du Libre, which aims to be a showcase of 
the best from Free Software and Open Source in Belgium. That's why we though 
about you, 'cause we are Ubuntu Fans (and mass installers ^^⁾. We've also 
invited other prestigious organizations like Mozilla, OpenOffice, etc. but we 
also concentrate on people and start ups who works in Belgium with Free 
Software (Drupal services for example).
