You're not the only one who didn't see it, apparently. I got quite a few submissions that contained a lot more than three images.
If you send me more than three, I will simply reply and ask you to select three before your submissions will be accepted. They simply sit in e-mail limbo until you narrow down your selections to three. If you don't reply with your selections, none of your images will go into the running at all, mostly because I will probably forget they are sitting in limbo in my in-box. That may sound a little unfair, but submitting more than three images in the first place is unfair to the other members submitting one, two, or three photos. This project is enough work that I don't have the time to PRE-narrow things down on an individual basis before I do the real thing.
Some people are also submitting without their screen name, location, and rats' names. Please also be sure to include this information when you submit... by the time we get down to the final votes and it's time to get it all together to upload to cafepress, the submission e-mails are LONG gone, and I have no information to go on, including no one to contact. If you submit the information with your photos, as requested, everything goes a lot more smoothly.
So, please help make this project easier for me, and fair for everyone else, by making sure to follow the guidelines.
Thank you.
