I am new to Project-GC. I have maintained a list of the challenge caches I have found over the years and started comparing it to the list reported by Project-GC. I've noticed several discrepancies: primarily caches that should be added to Project-GC's list, but also some that are on Project-GC's list but really aren't challenges. Is there a forum to submit these discrepancies, or is this just busy work that takes time away from more important development efforts?
