I recently encountered an answer by a user who has left the site for medical reasons. The answer, which was otherwise well-written, contained a minor error. The author's intention was clear, so I was tempted to edit the question to fix the error. Instead, I opted to leave a comment explaining what the author meant, then ask about the protocol for such answers here. If an author is not available to respond to comments, should we edit the answer or just leave a comment?

The question is here. The error is in the sentence that begins "For example, ...".
