Hi! Your user page category has been changed to Category:Hitchhikers in the Netherlands because from now on this (along with the old Category:Hitchhikers) will be a standard categorization for hitchhikers on hitchwiki.org (see this discussion here for the reasons of doing so). If for some reason you don't want to be categorized by country, feel free to delete country category on your page leaving only a standard Category:Hitchhikers. We hope you don't mind, though.
