Country and city are post metadata, not separate sub-spaces. Posting about Colombian visas? Goes in Visas & Immigration with country=Colombia. Don't ask for an "Italy Visas" sub-space — we keep topics global so wisdom transfers.
Be specific. "Where to live in Medellín" is hard to answer. "Quiet neighborhood near coworking, $1500 budget, 1BR, dog-friendly" is easy.
No drive-by promo. If you sell something useful, the vetted directories are coming. Don't link-drop in threads.
Spanish welcome. Code-switch all you want. We're here.
