That's great that you live in Windhoek and can contribute local knowledge to OpenStreetMap. Maybe I can get your understanding for the differences in the entries I am concerned about: OSM distinguishes between the tags for suburb (https://wiki.openstreetmap.org/wiki/Tag:place%3Dsuburb) and neighborhood (https://wiki.openstreetmap.org/wiki/Tag:place%3Dneighbourhood) or quarter (https://wiki.openstreetmap.org/wiki/Tag:place%3Dquarter). This classification is more correct and also makes the maps in OSM more readable. Kind regards!
