A foreigner is a person who grows up in a foreign land. Foreigners are often highly intelligent and widely talented due to their foreign raising.
Note that the term "foreigners" is not relative to one's own country. If one is picky enough to require a location of reference, the place one is foreign to is in relation to the imagined land of Route 50, whose member base is predominantly American. Among notable foreigners are Electron, and possibly Nick, who is definitely NOT an admin.
