Ups, It seems I started a long discussion. Sorry for that, because I wont to do this. Maybe I didnt explain my question correctly - I'm not a nativ English speaker and my knowledge of English isnt the best. I was only a little bit confused about the "situation" on the map of Europe, because on the map Greenland doest belong to Europe (it is grey) but on the text section under the map, Greenland was listed. Of course most or more or less everybody have not this problem, because Greenland isnt a typical destination for traveling or geocaching, but in my profil it is listed, because I like to travel to such "remote" destinations. For me and to close this topic it would be enough to add this "country" to Europe (filling with white or green).
PS: At school I learned that Greenland belongs to Europe, especialy to Daenemark (in political context). Geological it is situated on the north american plate. When I spoke with some natives they are thinking they belongs to Danemark, but the want to be indepentend, but Danemark paid every year ~60 000 000 DKK to Greenland - so in my opinion they are not independent.
