Justpeace.org is an excellent site. Go from there to Better Times Info (http://www.bettertimesinfo.org/) Don't mean to be a name dropper, but Bob Waldrop is a very interesting (and nice) person. Track him down via Google and you'll see a little of what I mean. I've corresponded with him off and on for several years and he always has something interesting going.
[Edited to say that Better Times is chock full of frugal ideas and encouragement!]
