Just pointing out that Coinographic paid the exact bounty or prize they offered... 0.25 and they paid on the date they said they would with no issues. Thanks Coinographic!  Looking forward to future design contests. 

Just an idea... perhaps only allowing those who submit designs to vote. Possibly giving each person 2 or 3 votes. With the rule that you cannot vote for your own design.  Might be the best way to get a true count... Also, perhaps to erase any accusations of copied submissions, make one day, the submit design day... So, if contest is announced 9/1. and ends 9/30 at midnight, make 9/30 submission day and everyone posts their design whenever they want (or can) on that day.  This way, if people are afraid their design would be copied, they can just wait till the last hour to submit, knowing no one will copy and be able to get it in by the deadline.

Also offer a bounty perhaps for best idea for a new voting process.  In this case, see the portion of my comment in italics above. lol
