Hi, Debbie.
I think actionwoman just about covered everything. One thing not mentioned is the "panic button". It answers questions and offers advice for things like if you've used up all of your points for the day and you're still hungry, or if you've hit a weight-loss plateau. I really like WW online, because I don't have time to attend weekly meetings, thanks to my crazy schedule. The convenience is great! You pick which day of the week you'll "weigh-in", and on that day when you log on, it will ask you to enter your current weight. Your weight is charted on a graph, so you can view your progress.
I used the 3-month special they're offering for $59.95, which is cheaper than attending weekly meetings, too. It's been 4 weeks today -- 10 pounds down, 40 more to go!
I think they even offer a "diet buddy" program, but I haven't looked that far into it yet.
Good luck, Debbie! Let me know if you join.
Chris
