Gotta second the PRI forums:

Much less moderation than here. More on social justice and the ethics.

Homestead.org has very friendly forums. Like visiting on the front porch.

Homesteading today has a lot of small farmer stuff. There are some folks into organic, but most folks there are not into organic. Again, not moderated as heavily as here.
