Well, since I'm not on the staff with this any more (Thank god, my schedule in school this year is horrendous Homework wise), I'll post my suggestions.
-Select a panel of four judges. These four judges stay forever until they ask to leave. Make sure that they know they will be judging more than one month. The fifth rotating member will be the previous winner. It's obvious that member participation can't go much farther than entering parks (

).
-Bump up theming to 20 points like I had originall planned (

). It's obvious that the community tends to lean towards the better theming, so this should be huge in points, even if certain aspects are picked apart in seperate areas. Sure, the seperate ideas of theming are produced, but "theming" in general is more about how every "theming" element fits together. Big Diffie.
-You MUST have an overall power over the judges. If they all pick a winner, but you don't feel that it meets the criteria for a VP (as you so stated a few posts below), you need to step in and for the good of the competition pull that months voting. Even if you extend it to 2 months with those parks in the pool for runner-up and have a mega comp, to just flat out restarting, something needs to be done (obviously). Now that I'm on "the outisde looking in" so to speak, these things appear more clear than they would had I still been on the project.
-DON'T release judges names until the next VP round. If people don't like the winner, I don't think the judges shold be named until the water "cools off". This just gets them competely out of the ring of fire so to speak. I know you don't like the idea, but you do need to take the blunt of everything said about the VP

. As it is your project, you are the head, and the judges shouldn't have to take scrutiny individually, but as a whole along with you. No one knows who scored for what, but they now know the judges names. I sincerely hope that no judge has been pm'd about this.
Anywho, those are my suggestions. Take 'em or leave 'em.
