There are already some French language forums on APUG:
but the darn things with us Francophones is that we tend to speak English very well online... So we keep yakking in the Other Tongue.
A while ago I started a Montréal social group, which I'm sad to say did not show much activity lately:
Perhaps a Forum would gather more attention, and be useful to anyone travelling to Montréal/Province of Québec. I think it should welcome bilingual discussions, given that both Francos and Anglos are part of the fabric of this city, and of this province as well.
My suggestion would be for a Montréal subforum first. Later, if interest is shown, a broader Province forum would be interesting. Or one for Québec City, depending on interest.
