Here are the issues I ran into running this contest, and what I'm going to do moving forward.
The rules sucked. They were obscure and wishwashy. This was part of the design, since I wanted to figure out how to run such a contest. Moving forward, the rules are going to be 100% explicit from the get-go, in the introduction post to the contest and be thought through better.
The voting system didn't work, and no matter how I do it, using SMF's polling system for this is broken, regardless of how convenient it is. Future contests will have a PM format with one voting stage, but it's going to be much simpler and more useful than the haxxy system.
You'll be required to rank each map in a given category from first to last place, with a separate ranking list for each category. You are encouraged to provide feedback for the map author, which will be forwarded to them if it's not destructive or excessively unfriendly.
Users will require five posts anywhere on the forum to qualify for voting, but when and where those posts are made doesn't matter. They can even be useless posts. This is solely to discourage the usage of alt accounts for voting and make it easier to figure out which ones are alts.
You will only be allowed one entry total, and you'll be disqualified from other categories if you do win in one of them. The limit on the number of entries is to encourage people to work as hard as possible on a single map, and simplify judging. Normally, this would be hard to deal with, and would cause precedence problems; however, the forced tiered voting system prevents such problems.
Entries will be required to have more than basic art. My standards aren't very high, but since this will be judged subjectively, give your best effort. Cortraduct is barely on the edge of having enough art, for example.
