Hey LentilBean...
Please do check out both the Vegetarian Chicks forum and the South Beach forum. Both are wonderful, active groups with tons of tips, recipes, etc.
We also have forums by age range, and by amount to lose, including the 100 lb club, ANOTHER active, wonderful group of those on their way to losing or who have lost 100 lbs or more. You can also join miscellaneous clubs, challenges, etc. There are a LOT of places to explore!
So look around, find a spot, settle in, and get to posting. Can't wait to get to know you better!
