I totally agree with Tuttle about voting rules - especially the anonymity of entries whilst voting is taking place, and all votes to be hidden until the winners are announced. I also think that two months is a reasonable amount of time to keep a contest open - any longer and it loses its 'thrill' (it doesn't take a lot to thrill me!. It must be possible to allow participants to vote, whilst not allowing them to vote for their own image, though - isn't it?
