Hey Susan -
I'm glad you joined! I'm always so happy when lurkers come out of hiding.
A couple spots to check out - we have the 20-somethings, for those in that age range (or other age-range-based forums, if I guessed your age wrong). We also have forums by eating plan and amount to lose, and a lot of miscellaneous groups and challenges.
I'd encourage you to look around, find a spot or several, and jump into posting. Can't wait to get to know you better!
