Another welcome here to 3FCs.
I agree with you. I have read many places and this is one of the friendliest.
You will find lots of support and suggestions here.
I also suggest to just read as many sites as you can and when you find a group you feel "at home" in just jump right in. They all will welcome you with open arms.
I know there are a lot of young and old here.... slightly overweight to extremely obese. Just keep reading... you will know when you found the right group for you.
