Very nice to meet you!
On the main message board page there are tons of forums. Just pick one and join in. Everything from Buddy Up, Support, Success, Excercise, Eating Disorders, WW, Low Carb and Lowish Carb with WW. As far as the chat rooms - on the main 3fc page under the message board message there is chat room that you can click on. Or, at the top of the threads it invites you to join into the chat by clicking there. (Gee, I'm pretty sure that's how it works~I do it so automatically that I might've left something out!)
Best of luck to you! Are you following any certain eating plan, too?
Friends can be felt when not seen.
