http://www.dharmafarmshawaii.org/ You'll notice that the main website is "roses and daffodils" but then you click on rules which takes you to another page you have to click on, anyway 3 clicks later you get the harsh reality. Very stern tones "we are in charge and you are here to learn not to teach."
A couple years back there was a link to a blog of a participant in the Noni/Dharma farm volunteer project. The impression I got from her report was that the group was culty and weird and definitely pressured people to go to the chanting. While being pleasant, they were not all that cool with the outsiders. The atmosphere was not that fun and that the noni stunk to high heaven. There were several other bad reviews from WOOFERS that have disappeared off the net - no doubt cleansed by Butler's cadre of internet thugs.
Here's a video with Alan Yoza, an old Butler follower hawking the farm [www.livevideo.com
From the photos and video - everything looks poorly maintained, given the fact tha all the profits go to Butler. The blogger commented on the primitive surroundings. I guess they all think it's like going to the Peace Corps -- only you really don't contribute to humanity or learn much about organic farming while working there.
