Best thing that can happen is if the threads about it would die. I think any ideas that get thrown around on these boards give the family enough to keep hollding out for success. I won't speak for Mat but I was happy that we didn't have to send anyone else into that small stuff. Unless every cave is blown out this winter I think I have done my last cave dive there for a long time.
Perhaps you could ask Cave Diver to close it? He opened it.
I will say there's been loads of good info presented here about the dangers of cave diving, the amount of training and skills it takes to dive a cave safely, and what it takes to recover those that don't make it out.
