I've reached out to everyone that has been drawn so far, either via email or as a reply to your comment on a post. That being said, we had two posts that received no comments at all, but I'm still going to give those prizes away. I'll be pulling names from the hat of commenters from the entire tour run and they'll be awarded those prizes that did not see entrants. I figured this was the fairest way to go about it.
If you got a reply to a comment from me, please shoot me an email, though I know in one case I did manage to track someone's email address down after I replied, so that one can be ignored if you got an email from me already.
Thanks for following the tour!
