We've come against a newbie that insists that he edit his question with the solution. When someone reverted the question to the original, he objected.
This question is a followup to How to handle solved problems (answer the own question?) I read the FAQ and noticed that it does not mention the convention that the question is not edited with the solution, but that you mark the answer which best answers the question.
Should the FAQ be updated to note this convention? Newbies won't immediately know to look in meta for this convention.
