I think this thread should be deleted, and replaced by a new one with a fixed set of rules.
There would have to be agreement over rules first.
If it were me, I would just remove all the rules, and just have a general mapping contest. If you really want good-looking, playable maps to come out of this, then it would be a good idea to put as few limits as possible on the mappers' creativity.
Certain rules must exist for clarities sake, like a time limit, procedure for entering, clarity about what will be judged and who will do the judging, clear distinction of what will be allowed.
If we take digg's example of letting even maps in that are already released, without adding any rules that would mean I could nick a .map of the official maps and brighten it up. Although no judge would award me any price except the cheapskate one it is something you would want to discourage.
Same with for example pulse. It's already released. I know soubok has plans for it and might even have worked out some glitches while waiting for the 1.2 mapping options to become available. As a result while a timelimit would limit any mappers starting anew soubok has a practical, beautiful, playtested, known map which he would get an extra month to improve upon an already great map.
I'm not trying to say they aren't interesting because they certainly are but instead before you start the new competition have a precompetition judgement of maps already released to determine the best of them and take them out of the new competition.
Edit : Is anyone even participating in this contest? It's looking to me like it's dead before it even really began.
1 or 2 but their applications got lost in the discussion of the rules i think.
