It'd be a bit tough to plan that I'd imagine. I posted my lynch on ste shortly after MaD asked me to sub in, it'd be nigh on impossible to plan that so quickly when you consider I am in a different time zone to everyone here.
As for Zhuorb, I'm not worried about him being Mafia. We shouldn't allow him to go under the radar, but then again, this is how he always plays, perhaps a couple of questionable posts here and there. Considering my knowledge of his play, I'd suggest he's more likely a bored townie with little to add right now rather than Mafia.
