Ning sites are very popular social network places in Internet where people meet & discuss things.
We can use them in this course to "multiply edge" as much as we can & wish.
It's pretty intuitive so if you haven't used them before just jump in & try it !
You can start by practicing with a group we set up for Integral Permaculture in the quite busy & excellent Transition in Action Ning - please do show us to any places where you chat about stuff that might interest us too, buy putting a note in your blog here with the link!
interesting interview with the CEO but a little out of date: no longer free option
(if you set one up, you can use any existing ones for free)
