As far as I know they are not doing ANYTHING these days.. I know they are older fellas from the midwest and heard that possibly they fell upon some bad health... Long story short they showed people the way in organics for 20 something years at least... when I first got into cannabis growing they were the mentors of my mentors... so they must be old...
The site 3lb.org is in no way affiliated with the 3lb's just some guy attempting to capitalize on their name.
3lb info is great to read, though watch out with reusing mushroom compost on your beds repetitively without a way to flush salts
