Hi, what a great thread, so many good ideas for low-cost weight loss resources.
Here's one to add: if you are having trouble sticking with it, check out
Weightcircles - Weight loss support site with free membership -- it's a social network for people losing weight, and it's totally free. You could keep using this site and that one as well - it's different, gives you a place to blog and put up pictures, etc.
Good luck!
