Hi Steve,
I'm not talking about a badge being "taken away" but of "giving it back." I've had the project badge for over 2 years and have yet to do anything to promote the project. To tell you the truth, I feel a bit guilty when I see it on my home/personal profile.
Please understand that I don't have any dislike for the Mayflower Project, just not enough hours in the day to work on it. I am contributing several hours most days to another project in which I have great interest, as well as a few other project where I work occasionally.
