There isn really contact between Dutch and French speaking people in Belgium. Why not create a Dutch local chapter and a French one?
The advantages to have a unique local chapter instead of two are: • We can promote collaboration. On Wikimedia projects, we work to share knowledge and collaborative work. We should show the way. • We’ll have a greater userbase. • We’ll have more credibility when dealing with press, institutions or authorities. • We can take in consideration English-speaking people. • The foundation have until now only accepted one chapter per country, according Anthere (but not according to Requirements_for_future_chapters#Geographical_base) • We’ll be able to offer trilingual presentations or conferences in Dutch, French or English.
