Interest Gathering: No-Nag Challenge?

I'm sure many of you have heard about "eating from the pantry" challenge or other similar money-saving challenges. I recently challenged myself to go without nagging for all of Lent, and I was pleasantly surprised with the results. I'm considering writing about the experience here, and setting up a no-nag challenge similar to the blog challenges I've seen, but I'm trying to gather interest first. Are any of you out there interested in participating? All participating bloggers would be invited to share their blog links throughout the challenge - and it's a great way to reduce a bad habit!
