It's quite common for new users to "answer" a question by posting.
Yes, I have the same problem. Could you fix it?
I'm suggesting that we add some default text to the answer box like "Type your answer here. Please only add solutions. Do not post just to say you are having the same problem" for users with less than a certain amount of rep (50 sounds good).
Similar to the Search default text, this would disappear when clicked on so as not to be too disruptive.
This SU question is quite bad (4 "me too" answers).
I know we can flag these, but that adds extra works for the moderators.
