When we started the Contest, we originally wanted to accept NEW maps only. That is why you will probably find maps on the list that are not yet available for download - but will be soon. Anyway, we didn't receive very many registrations when the rules required unreleased maps - so we allowed for existing maps with a few modifications. That's why now there is well known names on the list, too (most of them have been modified for the contest).
We'll be announcing the winners this weekend. How we are going to handle the map downloads is not certain, yet (we might be running into traffic problems if we handle it ourselves). We'll see.
