At risk of diverting the purpose of this thread, I seriously don't understand why reverting to the long held rule of one entry per individual can be considered "oneupmanship" .  Some enjoy the challenges but don't have the time to generate multiple images for that purpose.  For those that do have the time, why is it offensive to ask that person to select the one they think is their best for the challenge to upload?  Why can't it be accepted as a challenge to submit your best effort at a particular theme and that is simply all there is to it?

I sincerely hope no one who frequents this forum believes the folks here are anything but friendly and helpful in all matters.

When I was a kid and growing up with a half dozen or so close buddies in the neighborhood.  we would occasionally come up with all kinds of "who can____ the best, longest, furtherest, most, highest, slowest, with eyes closed, etc..." dares and contest.  Probably, in most cases, the winner could be predicted in advance but that didn't matter.  We all dug our heels in and had a great time trying. 

I hope no one here holds back and sits on the sidelines.
