I would very much love to help with this project, but sadly, I am not experienced in any of Click-Team's Products.
However, I can offer suggestions for rules. It could at least impact how this project becomes.
Obviously, there should be a group of people who will judge the levels, to see if they meet the expectations of the project (Length, Difficulty, Enemy Placement, Level Design, Graphical Aspects, the list goes on and on...), but it should be placed upon a deeper level than 'yay or nay'. I honestly think that said judges (and participants) should be accustomed to both the developing aspect of Click-Team's Products, and also be experienced in the various aspects of Worlds.
It might also be helpful to create a template to track the progress, like:
ZONE 1: "ZONE NAME" DEVELOPED BY: "DEVELOPER'S NAME" ACTS: "# OF ACTS" PROGRESS: "00%" (so on and so forth...)[/CODE] [size=1](If I sound like I'm repeating stuff, or am saying something that is obvious, just blame it upon the fact that I'm new to SFGHQ.)[/size]
