I am an occasional contributor to OSM. I am based in Sheffield in South Yorkshire although I also spend time in Asturias (Northern Spain) with rare forays to Lithuania, Slovakia, Kosovo, other parts of Europe and Palestine. I use a Navilink GT-31 and track on foot or by bike. My PC runs linux (openSUSE 42.2) so I use gpsbabel to convert to gpx and then I use JOSM to edit. I have also started contributing to HOT tasks using armchair mapping from Bing imagery.
