It's this dude's job to determine whether a text contains any errors of doctrine. "Censor" doesn't mean he (and yeah it's always a male surprise surprise) cuts anything or prevents anything from being published it just means he says whether or not the written material is free of errors of doctrine. (In the middle ages if he didn't sign off the work would not be suitable for distribution and the author if he resisted correcting it would probably be burned at the stake but they didn't have toilets then and now we do; long time ago.) Which means he has to be really good at *catching *errors of doctrine; has to see the often underlying or imputed doctrinal implications of things. So for this reason I nominate Rabs as the LUG's Censor Librorum. It didn't even occur to me to relate that passing "asph" comment to the hotly debated issue of whether the contempo Leica glass is "hard" etc. But of course he's right -- it was a direct hit. Awesome. That's like watching someone nab a fly with chopsticks. Nothing gets by.
