Okay, well, after reading your statement again, I see it was somewhat ambiguous as to whether or not you were allowing "something created by someone else." I thought at first you were making a remark about "not" submitting something created by another. I'll leave them in place unless notified otherwise.
Thanks. I'm looking forward to seeing the many entries submitted! Hope I have time to view them all!
Just a suggestion, but, perhaps next year you could break it down to a "best in category" even though they may not win the grand prize. We could still recognize those in each category.
