this site has definetely got the best forums
not going anywhere but others I find useful
www.stretcher.com
www. cheapskatemonthly.com
www.frugalliving.about.com
do a google search and see what you find
I also really enjoy
www.simpleliving.net as it focuses not just on being frugal but on a simple nonconsumer lifestyle
as to beliefs- see what you find comfortable- I am not a Christian but find many christian based sites very useful- but move away if the posts move to far from being frugal-, which is why I'm there, to other more sensitive and potentially excluding topics ,
