You know what they say, there’s no such thing as bad publicity, and the site broke all records yesterday for the number of hits!
I can’t answer for Stephen, but some challenges do let you count previous finds, some like the Alphabet Puzzle Challenge don’t. It was FE who suggested that, not me. And yes, you can count the same caches for both challenges.
Phil is currently working on seeing how many squares have caches, but I would imagine that the Minor Challenge is probably ok now. Trouble is there is no query you can run that identifies the DNP only caches. 13 miles from Postbridge just about covers all the park, but you get stacks that are outside as well.
