Nope, because I always post on my phone and it doesn't play well with chatrooms. Otherwise though, I probably would. Instant access to support if you're having a bad day or have a question sounds good!
There have been times I would pop in and see who was there--weight loss is a major thing in my life right now and I don't always want to talk about it with real-life friends or my husband for fear of over-talking them.
