I use it. There is an online tracker thing, that you can use to track points, body measurements and your weighloss, and if you like numbers like I do, then it works out rates at which you're losing, and stuff. Makes a graph of your loss.
There's a recipe builder too, which I find useful for working out what points are in my non-WW meals and recipes. Cakes and stuff, cos I do a fair bit of baking.
There's quite a lot more recipes available too.
I took it up as the 3 month bargain thing. Not sure yet whether I will cancel it or continue once the three months is up, but at the moment it is helping me through a bad patch. BUT I am too lazy to keep a paper diary, and that would probably do the same job...
I don't really use the community section, I don't like the layout, the design of it but when I have, everyone's friendly, but honestly not a patch on this place!
