In this question on the parent site there's the following blockquote
! LaTeX Error: File `hypernat.sty' not found.
Now, while I'm typing, it's correctly shown in the preview. After posting, however, it seems that the "!" marks the blockquote as class "spoiler", so it's only visible on mouseover (and the "!" doesn't show up anymore, of course). I'm curious if the same will happen here.
As I didn't ask a question so far, I think I don't break the "one question per post" rule if I ask this related question
:-): What is the "correct" formatting here, blockquote or code block?
Thanks, Caramdir, so it's a feature (something similar has also been discussed on math.stackexchange). Even though it is, do want it here on tex.sx? At least I can't think of any situation where we'd care about spoilers. So I do ask two more questions, sorry: Is it possible to turn this feature off on tex.sx, and if so, do want it turned off?
