Today I realized that almost 30 of your comments had been shuffled into a "moderation" folder here...and Google failed to notify me that there were comments to be moderated. Many of these comments were to let us know you had a challenge going - and because we didn't see the comment, we failed to post your challenge.
I am so sorry about that! I hopefully have now corrected the problem. Those challenges which are still going will be posted soon...for those I missed, please give us another chance!
