On my question I noticed a message:
We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.
It's located right under my question. Out of curiousity, how did it get there, who put it there and why is there no information (maybe a link leading to a FAQ page) there?
