I was poking around the internets. Bored one night. Stumbled upon the site randomly after looking up forums in general.
I was already a member of Weight Watchers for about 6 months at that point, so the topic of healthy weight loss was (and, of course, still is) a big deal to me. It only took me a night of lurking around to realize how amazing the community is.
Links to stories, talks about the merits of certain plans or ideas about weight loss, fitness ideas, and most importantly the positivity and "you can do it!" attitude. It's very approachable while many topics remain engaging on more than just the usual "eat less" information. It's personal, but still supportive of everyone in a healthy way. More so than any single other weight loss site I've ever come across.
I've been attached at the digital hip to 3FC ever since.
