Hi Mike,
Well...anything can be "edited" as long as no one "steals" from another. Conceivably you could change your entire entry, as long as it's original. Hypothetically, if two entries were identical in some way, the first one posted would have "dibs", correct? It wouldn't be very wise to copy something that someone posted "before" you, would it?
Most of this falls into the realm of common sense. If someone copied my entry from the first contest they wouldn't have success with it, because it's been done before. Leigh likes to be both challenged and surprised.
And, if someone did cheat you guys would be all over them like...flies on manure! :wink: The world would hear about it...literally!
This contest is very "out in the open" and "above board". That's the only "right way" to do it and still send everybody home happy.
All the best.
