Hi megpark!
As Jay said, this is a HUGE site! I've been here since last June and STILL haven't checked out everything! Pop in anywhere...no special invitation required! Read and post and think and learn and offer your two cents when it feels right!
There are people here who have lots to lose and many who are working hard to maintain their weightloss that they have worked very hard to achieve. Many have eating issues and eating disorders and many others who have yet to figure out where they match up because they are in the process of sorting out their lives.
Weight issues are a pretty serious business, but you will find lots of humor here!

Sometimes it's helpful just to LAUGH!
Welcome!
Cheryl
