Hey, great that you finally answer us ;)


[OSM Notes] are for marking an error in the map data or to give some additional information, for instance the missing name of a street or a missing address.
They are not necessary to note that you did a change, as there are OpenStreetMap-Collaborators that look at each and every note (in Switzerland) to fix map data.
