Hi Becky, it's been a while since I looked in to it, but I think you get the weekly material delivered to you with the online membership, plus you get the online tracker.
The WW forums are free, and you don't have to be an online member to use them. I've found their forums very, very busy and hard to keep up with a set group of friends to weigh in with, or build accountability with. The threads sink several pages back in the matter of a couple of days. I think the support groups here are much better!
