Announcement

At some point, the Differentiator Revisited website located at www.geocities.com/tws490 will become inaccessible. In an effort to save the information included at the site we are moving the material to what we hope will be more permanent sites. As the sites are developed, they will be announced (See Related Sites... below). It should be noted that corrections, improvements, and additions will be made even after the sites are announced.
