The main reason we set limits on the challenges is to get folks accustomed to working to a deadline. If you never intend to try to make money off your maps then, cool, challenges are there to just be fun for you or experiment with new things. If you do hope to take on commissions in the future, you will have to get used to deadlines and other parameters set forth by the client. So for that reason we say, no old maps - just brand new ones. Of course if you have an old map that fits the criteria and you wait until like the last few days to post it then we might get suspicious but there's no way to prove anything so it might slide by. That's one of the reasons why folks post updates along the way - to show how the progress is going. The tag grabs the very last image in the thread to use for the thumbnail compiler that we use to post up all of the images for voting (well more specifically the very first image after the very last tag). Folks often forget their tags or do them wrong or forget to title them properly or put them in the wrong subforum so we CLs go in and fix them up when we see them.
