Not really, what other rules are there for game threads?
You just explain the one rule, and someone understands. If no one's reading it, and they probably won't, then there's not really a point when it takes less time to explain the single rule than to go to the rules thread, and either copypaste the URL or the rule. The only reason it would be a good idea is so you could say that there's no excuse for not knowing the rule or whatever, but that hardly makes sense because it doesn't really seem like something worth punishing, it's more like a mistake.
