I don't think there are votes for people at all...every time I have seen a photo tourney...the best picture wins, that's the end, nothing more.
The reason why vroom_skies ( a moderator ) has won so many is obvious. Click on that little link when he submits a post, the link looks like this: My Photography Website
Take a look at his site, he is a professional picture taker...duh
He shoots some of the best pictures ever...ya...he wins a lot for a reason.
