A couple of weeks ago, I was sent a link to a place called the Goodman Center. http://www.thegoodmancenter.com/  It's run by a man called Andy Goodman – who I don't know personally – but who wrote a wonderful book that I read a few years ago.

It is called Why Bad Presentations Happen to Good Causes. Andy focuses his work on helping good causes (environmental and otherwise) reach more people more effectively.
