I have rules and such for the challenge spoken about earlier this week on my blog. Note that this is just a challenge to people who *want* to do it...you don't have to. I really hope to get some participation from here as well. More people doing this means more awesome photographs to look at!
Oh yeah...and if you are going to participate, do me a favor and post a comment. That way I can keep track of everyone who decides to do this. Make sure to post your forum name as well if you use a real name or a different nickname to post the comment.
