Just Frugal (www.justfrugal.com) seems like a good website/blog/forum to join. They have a variety of forums dedicated to everything from the indulgence of the day to debt reduction. I've just joined and introduced myself on the "Introduce Yourself" forum and received some welcome posts. At least I know it's an active group. The posts are all recent, too. I look forward to lots of frugal sharing there.
I also visited Coupon Mom. Not so great. So many ads and sponsorships it was hard to tell what was legitimate and what wasn't. In fact, it was so laden with ads that it was overwhelming and my overall impression was let's see what we can get this consumer to buy. So, I give that one a thumbs down.
