I have just run into a question where the answer was posted in the comments section, immediately followed by a "thanks, that worked, how do I accepted comments". I copied out the comments, added a couple of lines, put a thank you to the original commenter and posted it as an answer. Is this appropriate? I feel like I am steeling rep from the original poster, should I delete my answer and let the original commenter come back (in who knows how long)?
What are your thoughts on this matter?
