This is different from the request in mark a comment as answer to a question.
Sometimes a comment should be an answer. Sometimes an answer should be a comment. For some reason, people screw this up. I'd like to propose a ability to convert between the two.
For the case of an answer with comments, converting it to comment should convert the answers comments to comments on the question below the migrated answer (which is now a comment). Comments that are not @replies should become @replies to the answer-turned-comment.
For the case of comments turned to answers, I think its straightforward.
I propose the following migration privileges:
- If you can edit questions you can convert
- If you asked the question, and have at least 200 rep you can convert answers and comments
- Anyone can propose to convert an answer to a comment or a comment to an answer.
