I love the idea of the challenges and can't wait to get started, but could someone, for the love of Mike, post one message that contains the actual challenge, deadline, etc? I don't want to have to wade through 10 pages of messages to figure it out.
I saw that someone suggested that they host the rules and current challenge on their site. While that's a generous offer, I think it'd be better to just create a general rules thread and have the admins lock it off from replies. Likewise, for the current challenge, once it's been finalized, I think a thread, once the challenge has been defined, should contain the details on the first message (easy to find), with WIP images below. Then, when it comes to final images, I think there should be another thread that says something like "So-and-so Challenge: Final Images" so there is no confusion about where to place them and look at them.
