PS
Forgot to mention it on Community.
EST and Erhard had some great things in it. There were quite a few of that type program out there, LifeSpring comes to mind. A lot of bright folks learned a lot and the world is a better place for it.
Even L. Ron Hubbard and Scientology has some good stuff. There are some pretty well put together people in that program.
And those programs are certainly more constructive than fundamental Christianity, for instance. That's not saying much, though. (Speaking of cults.)
