Forum:Most active communities

How do you know who are the most active communities? (http://community.wikia.com/wiki/Hub:Most_active_communities ) I would like to know so I could update it for the french wiki (http://fr.wikia.com/wiki/Th%C3%A8me:Wikis_les_plus_actifs ) which, for the moment, pretty much consist of people updating those who were already there and adding their wiki if there are enough contributor. --4me 23:46, August 11, 2010 (UTC)
