Aliasing: wrestling_ring and boxing_ring to ring_(place)
Reason:
This two tags are really similar, and IMO almost nobody would see difference between those two when searching for porn. But if alias is not okay then let's make at least implications for someone who just want to see some kind of ring.
I'm also not sure if ring_(place) is the best name for new tag, but I can't find anything that fits better.
