Late last year, as part of our resolution to get our finances under control, I joined the Women in Red message boards over at msn.com. The (mostly) women on these boards provide moral support, good advice, and help hold me accountable to our financial goals.
I am an active member on two boards, the West Region Racers, which is all about paying down debt, and the Controlled/No Spend board, which is about sticking to your budget and finding those little leaks in your spending. Both are helping me to stay focused on long term goals and allow the occasional rant.
