Are your referring to the website or the concept? Concept wise I can tell you that it is wonderful! DH and I started the DR plan in January (2011) and we've paid down more on our credit cards than we thought possible. Sure, it's been hard and we've had to change our life style a little but setting goals together and talking about our finances every day has brought us closer together. We love talking about how great our trip to WDW will be when we can celebrate being debt free. We're already making our plans for playing off the mortgage early.
I wish the LLNO website would come back up. I didn't post there often but it was nice to read about other people's goals and accomplishments.
