Proposal: Sports Officials
I would expect that Sports Officials would be a relatively small community if left on its own, but I don't see any reason why it shouldn't be merged in with Sports to create a bigger and more thriving one. Most officials are also participants, especially at lower lewels of sport. Some questions about officiating could probably be answered by expert players as well as by officials, so I think it would be beneficial to combine them.
I would suggest asking some officiating questions on the sports site to confirm that they arae good with this.
