Sometimes a comment will suffice to answer a person's question. This may be because they are only missing one small step in the argument, or because they can be pointed to a resource that answers their question fully.

In such cases, it could be a good idea to be able to accept a comment as the answer to the question, in the same way that answers can already be accepted. (It may not be appropriate to award 15 reputation points in this case, however).

The advantage here would be that questions answered by comments could then be removed from the 'unanswered questions' section, making it easier for other users to identify which questions still need to be resolved.

What are your thoughts on this?

• I'm pretty sure this has been discussed before and was rejected by the SE team. If you see a comment answer, you can always leave an answer yourself (make it CW so you don't look like you're gaming for rep) with credit to the user who left the comment. There is a chat room (the crusade of answers) where you can solicit an upvote to remove the question from the queue. – Alex Becker Apr 10 '14 at 21:00
• OK, thanks. What were the reasons for the rejection? Can the discussion still be found? – Frank Apr 10 '14 at 21:02

That said, obviously such an answer still does need to $$(i)$$ give credit to the original comments it's drawing on and $$(ii)$$ not just copy-paste those comments.
