Well Sign Up for the Joy of Less is still doing the same thing; I can't seem to "join" so maybe it's just not trackable and the little badges aren't badges. Can't seem to get anyone to reply about it either.
On the main page for The Nest (http://www.mnn.com/the-nest) there's a little pledge site thing has a checkbox for completing it but I can't click it. It just bounces off. Am I supposed to be able to "check" or "complete" it like it's a tracked quest?
I've done "I will use reusable bags"! I have a foldie that stays in my backback, a stash of reusables in both of our cars, and 2 in the entryway to grab on the way out just in case!
