Hello http://sunsite.unc.edu/london/permaculture/mailarchives/pc-homepage/msg00041.html I followed the above link and found the information to be out of date. Is it possible to update the link to the Permaculture web site to http://www.permaculture.co.uk Thanks! But does the msg00041.html page being a mail archive makes upgating a problem??
