Some users ask questions and go away without accepting any answer even though the answer is right, Can the moderator have the right to accept answers if it is right and the user did not react or comment the answer? also can users reformat the questions for better reading have no relation with reputation
I very often add code markup on questions or change the post type (from 'tool' to 'question'). Although I don't always do so, might be the best to inform OP about the changes I made (and how they can improve on this in the future).
It's a good point about an answer that seems right may not actually be what the OP is looking for. However, there are occasions where the OP will comment with something like "that solved my problem" to indicate that the answer is correct, but it wouldn't be marked as such.
