This isn\'t a very compelling argument coming from a user called \"Stickman\" but the idea still stands. First names should be unique, last names not so much. I think in whatever next flagpoint the devs get to in developement there should be a family tree type program made. A person can register a family name as family. Each person who wants to use this last name will haveto check in with whoever established the family so that some random kid doesn\'t just start making family members for a family when the person who has established it doesn\'t think it matches with the families history or such. That way only your best friends and such will be your brothers, sisters, mothers, fathers, cousins, lovers, etc.
