It’s really not that crowded. There are often minutes, if not hours, between posts. Anyone can step in whenever they like.
It’s public because it’s a fun game which various members have enjoyed since it was first posted. It wouldn’t be practical to make it a PM thing. That WOULD prevent others from playing. Deep used to post there a lot. I hope he returns soon.
