Since Nightmare, Sevensins, and SmartRutter are usually asleep at night, I say we have an OP who's active during the night... Personally, I think AngelOfDeath is a good choice. He's on pretty much all night, and has shown a lot of maturity when it comes down to spammers and the like... At the very least, one of the current OP's should temporarily pass powers to him while they sleep.
