First Name: First 3 letters of last name + first 2 letters of first name.
Last Name: First 2 letters of actor's name, first 3 letters of hometown.

If there are less than the required amount of letters, it uses as many as it can.
Having that been said, I'm going to go out on a limb and say that your first name is Greg.
Anyway, mine is Gupra Jasan of the planet Prozac.
