|  This script adds a basic killfile to HSX forums. Click on the X by any author's      |
|  name to make them disappear until you may want them back. This is an update of the   |
|  classic HSX killfile. That script began as a modification of the Google Groups       |
|  killfile by Damian Penney, which he descibed as a modification of the Metafilter     |
|  killfile script written by Mystyk, with a bit of jiggery pokery applied.             |
