When reviewing new answers, I came across one in Spanish. I assume that English is the only allowed language.
The problem is that I can't find that written anywhere. The Help Center has some guidance for asking/answering questions, but none of these posts describe any rules about language.
Another example is our rule about posting
<pre> text instead of terminal screenshots. I know it's a rule because I've seen senior members enforcing it, but I can't find that in the help center.
It doesn't seem right to enforce rules that we only assume exist.
