I was asked this question earlier today. I've been going by the name of Freddy since 2003, despite my name actually being Brian.
When I first registered at EasyUO I thought that EA might be tracking people by their usernames - I was only 13 at the time...naive
I was watching Freddy vs Jason (horrible movie btw, hot actress) and just sorta borrowed freddy from Freddy. I have a few other names that I go by, but freddy has been my main name for anything involving UO. I want to change it, but I have no idea what to change it to and people already know me as freddy.
So, how did you come up with your name?
