Hey Ali!
We have a ton of places you might want to check out...the 100 lb club, for those on their way to losing or who have lost 100 lbs or more...the 20-somethings, for those in that age range...and groups by eating plan or for miscellaneous challenges.
So look around, find a spot, and get to posting! You can find all kinds of advice in the plan-specific or general weight loss support forums.
Can't wait to get to know you better!
