Sarah I am with you, I thought it was for onederlanders too! I always thought "100lb club? Not for me. Try 200+lb club..." I just found it today and am SO happy I stopped in!
Actually, even once I got it figured out, I realized that I don't really fit in anywhere. (Story of my life!) I'm not over 300, I don't have 100 pounds to lose, and I'm certainly not a featherweight! So I just float around and post wherever I feel like it.
