You mean each having its own category? For now I think it’s simpler to just have 1 topic per language. If the Local topics get very popular, we could consider adding categories for each language. Personally, I would prefer to wait until Discourse adds the ability to have “category-specific moderators”, as I explained here.
This header?
I’m not sure the header would support adding lots of flag icons. Maybe we could just add a link to the Local category? Or we could list the different language topics on the Community page. What do you think?
