Hey there
I have the Monthly Pass (which includes meetings and online as a package).
The site includes a Plan Manager which helps you to track your food, exercise and good health guidelines. There's a large database of foods in their system, as well as a Points calculator so that you can enter the foods you eat which don't happen to be in the system. Your Plan Manager then stores those foods, so you don't have to re-enter them each time. They just become a part of your database.
The Plan Manager includes a Weight Loss Graph, as well as a Measurement Graph to track inches lost.
The site has a ton of fitness and weight-related health articles. There's a Community section which includes message boards, community groups and even challenges that you can sign up for. I don't personally find that the community is
as helpful or friendly as is 3FC, but it's there and can be useful from time to time for WW specific needs.
I find it to be very worth it, especially the Plan Manager for tracking food. I happen to have an iPhone, and there's a WW application that I can use to track my food to my Plan Manager even when I'm out of the house. It's perfect for me. I'm always using it.
My experience with their site has been mostly positive. The only real negative for me is that there are places within the Community section (the message boards specifically) that tend to be clique-ish or a little blunt/snotty. But, the Community Groups are so much better, and I can simply avoid the areas I don't enjoy.
I hope that helped!
