I have asked for a code review in a post and received nice feedback. I would now like to implement the suggestions, and possibly get new feedback ("Yes, that was the problem, good fix" or "No, dude, you got it all wrong because...").
Can you please tell me what I should do, so that the person who bothered to answer the original question would be notified about this? Should I edit the original question? Should I post the update as an answer or what?
