A new PC wiki will be the solution to a group location for serious text file
and photo archiving.
I will have a look at PM Wiki.
I've just spent some time re-activating the permawiki at
http://permaculture.wikicities.com/wiki/Main_Page Mainly I've been
pasting in relevant stuff from Wikipedia which will hopefully then take
on more permacultural directions, as well as creating some basic new
articles on permaculture principles, etc, and thinking about ways of
creating spaces for the development of permacultural thought,
discussion, course and project promotion, etc.
I was going to try to flesh it out some more before making an
announcement here, but as i see that you are thinking in the same
direction maybe this will save some dupicated work.
