Hi! Your user page has been added to a Category:Hitchhikers since this is a standard categorization for hitchhikers on hitchwiki.org (see this discussion here for the reasons of doing so). If you want to be categorized by country, too, chose the country of your current residence from the categories on Category:Hitchhikers page (or create your own one if the country of your current location is not on the list - in case you need help with that, please write about it here).
The hitchwiki team
p.s. you can delete this msg if you want.
