My username is - as you've probably already seen above - Nw520.
I'm a rather passive contributer to OSM and can be also found on Wikidata, and from time to time on Wikivoyage DE, Commons and Wikipedia DE.
A special concern of my participation in the projects of the Wikimedia Foundation and the OpenStreetMap is to link data between each project in the best possible way.
