I posted a new Challenge a few days ago, and not one single entry so far. No, I wasn't irritated (in fact, I was caught sleeping, and I can be a bit grumpy when awakened)
Thanks for all the submissions. As per usual, the hardest images to find are those that require retouching but not restoring. In fact, those are so rare I used the last one I got as the April Contest instead of as a Challenge. In a perfect world I'd be able to post more Retouching Challenges than Restoration Challenges.
