Hi Lyssa Steponaitis,
Yes I agree...
Starting from the country level, and/or regional levels, then moving towards more detailed permaculture and related organisations (such as natural building)...
such a worldwide connection would be outrageous
In general, I think that with so many organizations around the world, trying to form their own niches here and there, such an occasion is a good time to sort of double-back and re-connect, and take the initiative by saying;
"Hi there... What has everyone been up to in your area for the past number of years?... Look what we created recently... Please share it out with your people..."
Permaculture might not be mainstream... but it has definitely taken off over the past number of years...
unfortunately many still go through the never-ending frustration of not being able to escape into their preferred way of (permaculture-related) living.. so to use such an opportunity to connect the clans, would probably be quite something
even if some or many of them come back with muted or no response... instigating the connection will not be lost
