when I visited your beautiful country some weeks ago I mapped some details. I was wondering how the former german place names are mapped. I mainly looked around in the area around Gryżyna (https://www.openstreetmap.org/node/31623371). Some places use name:de=, some others old_name:de=.
It would be good if there would be a consensus how to map those village names.
Thanks and Wesołych Świąt!
