I think that has to be a judgment call from you, bartmoss. After all we are never going to know if a hitherto unposted map had been worked up in advance of a contest - although we may suspect

I guess a good rule of thumb might be that if you have sketched out general ideas, world building etc, then that shouldn't count as working up the map (unless the contest is specifically about world building). It's probably best to explain in your initial post how much previous work you have done if you're not sure.
