Our unspoken system is to allow ungraded refs to pick up matches if we see that they have sent a VM. I can help you out though, my next match that needs a ref, I will come to you? Yeah, I can do that. Are you good at keeping your 48 hour bonus or nah?
OH, did not see you go after that specific battle. Just keep in mind that you cannot ref matches in progress without a grade. It is part of the rules. Take FF's other battle though? You got his permission, so all you need is the permission of the other trainer?
