Except for English, there are actually more posts in French than in other languages, because I'm French native and the main contributor of Sweet Home 3D. You can easily guess that it's easier and faster for me to answer to questions in French.
But I think there are really very few French threads which talk about subjects not seen elsewhere, probably this one about sloping terrains or this one about this one about installing Sweet Home 3D for multiple users.
