Yeah, that's how I got introduced to challenges. I thought I was so great when I came up with the idea of only using a single type, and then bam it was already here. Made me sad. But sure, go ahead and start posting your progress now. It's so much better than people saying "Oh, I've already done that. Give me credit for it now!" At least you're updating some. I sometimes start the challenge, and just type my update as I go, and then beat it, so it ends up being one huge post. Trust me, you're fine.
