I think its great that people are banding together and starting a contest, but let me suggest sign up be open thru the seasons entirety. It is kind of silly to try and promote activity on the site and then close sign up for a free contest with no prizes after only 4 days. WhenI ran the turkey contest team could sign up last day and it worked out great. The old deer contest was open to register a deer all season and up till a week after it closed.
Also, to encourage younger hunters, hunters in lower trophy producing states, etc I'd suggest having the contest judged partially on the story / journey of getting the buck. I'd vote for a guy shooting a150 inch 8 point with 4 years of cam pics, sheds, history over a one and done luck of the sit 200 incher. The story/ journey is the best part IMO
Anyway, food for thought.
