Hey DeltaGirl!
Sounds like you are off to a great start. We have groups here by age range (30-somethings, yes, if you just attended your 20th reunion?), by eating plan, and by almost anything else you can imagine, so look around. You also might want to visit the 100 lb club, our incredible, active, fabulous group of those who have lost or are on their way to losing 100 lbs or more.
I'm glad you returned to us, and can't wait to get to know you better!
