Hi! I'm new here... I post on the WW site sometimes though, but it's crazy over there.

I'm on week 4, I've lost 8 lbs. It was weird because week 1 I lost 3 lbs, week 2 I gained it back due to salt, week 3 I lost 8 lbs when I fixed the salt issue. Now it's week 4 and I weigh in on Thursdays. I see there's a thursday group here. Is that a popular day? How do you join a challenge group like the thursdays on this board, or is that a private group?
