Just from my browsing of other web sites - spotted a useful download courtesy of the International Institute for Communication and Development and a hat tip to Lucie Lamoureux for spotting it and making it available.
The download is available by clicking on the title of this post.
It is a collection of articles based on the experiences of non governmental organisations and howe they have used technology to encourage collaboration. They are using tools i have heard of such as delicious but also some tools like Moodle that I haven't.
If you do download, this please remember to give a hat tip to the person who found it first. Just remember that altruism as I have posted before is often reciprocated.
