If you've got a question about anything try our open questions forum. Chances are good that if we don't know the answer, we want to, and we'll find it together. Think big.

If you're at a loss for words you can jump straight into some community design ideas, designed to get everyone thinking visually.

We've also got super informative threads that go in-depth on compost remediation, phytoremediation, and biochar (terra preta).

You'll also find an unending flow of success stories that highlight some of the best examples we've found of solutions in the real world.

Here's a handful of other fine discussions going on right now:
using geographic information systems (GIS) for rehabilitation,
figuring out how much food it actually takes to feed a community,
challenges and solutions for re-greening desert ecosystems,
rethinking invasive species of plants, and much more.
