Scrubgenius is the Google Group where SubGenii can talk freely without Pinks bothering them. Only ordained SubGenius ministers who paid their membership dues are allowed to use Scrubgenius. It's online at groups.google.com. Basically, it's a replacement for alt.slack, which was abandoned to allow the kooks to roam free, biting and humping each other. Scrubgenius got set up by a SubGenius named Tater Gumfries.
