I was just remembering one of my first forum experiences four years ago, on a now-dead forum. We could request name changes anytime we wanted if we PM'd an admin. I had picked a name that at first was an interesting word, but later proved to be very embarrassing for me to bear. So I asked to have my name changed, but they wouldn't do it. I guess they thought it was a good name for me, although I thought differently. To this day, seeing that word still makes me blush. And I do remember what it was, but I'd rather not share it. It's too humiliating.
