Have you found this Permaculture site?
Just thought I'd post this for the Permaculture enthusiasts who might never have visited David Holmgren's site.
As many will know, he is the co-founder of original Permaculture.
Also worth mentioning, there is a reasonably decent entry on David in the Wikipedi, on-line: http://en.wikipedia.org/wiki/David_Holmgren
Here is a link that might be useful: David Holmgren's Web Site
