That sounds like complete BS! As far as anyone I know knows you post what you find regardless how many in a particular category. "It's not about the numbers" is frequently thrown about. That's certainly true it not about the numbers, it's about having some fun. It's not your fault if you find more waymarks than someone else. They shouldn't be able to tell you there's an arbitrary limit.
If this were the case and it was across the board, Waymarking would be a long way off from it's recent 100,000 waymark and BruceS (sorry Bruce don't mean to pick on you) might not have reached the goal of 5000. (Dang, that's impressive!)
If the folks running the figurative sculpture category want to play the game in such a way then perhaps then some of them should archive some of the sculptures they've posted. I didn't go through the entire category, but the groups officers have the following totals;
caverspencer - 2
robbdogg120 - 5
GA Cacher - 13
Math Teacher - 12
DANG! I have 9, I better be really selective in the future.... Whatever!
