I just surf about the boards, posting where the mood takes me. I can vouch for the ladies and gentleman in the 100lb club, we are a friendly bunch, and you don't HAVE to be facing that big a weight loss, we welcome anyone.
I also pop into maintainers, they are friendly as well, and sometimes it helps to find out what you need to do to sustain a large weight loss from those who are walking the walk.
And if you see a post from someone you feel you can connect with, you can private message them, and who knows, you may have made a lifelong friend
