The Silver Bullet project’s list of words was originally written on paper and known as the SB list. It was typed up into a plain text file called SB.txt. This file eventually contained 1425 entries. Each pair of words ( known as an SB ) was given a single letter classification. When they were imported into WordPress this code was converted into a Category.
