I teach Sustainability Education online and my students and I use wikis. I'd like to expand our curating of resources for communicators and educators focused on sustainability. Here's a link to the program I teach.
Online teaching allows me live in cabin in the woods and still engage globally! I'm in the Ottawa Valley in Canada. I grew up on a farm "down the valley" nearer to Ottawa. Now I live in a more remote area and I play in the great outdoors with my kids as much as possible. There is a confluence of awesome rural cultures here: old school homesteaders, new age homesteaders, outdoor adventure enthusiasts, hunters, anglers, cottagers, ecovillagers and reclusive artists!
