While going through old unanswered posts, I noticed that quite a number of them are in fact answered by the comments to the question, usually because the question is based on a simple misunderstanding or has another very simple answer. In these cases, it is inappropriate to show them under ''unanswered questions'' (or to bump them with priority under the new random bumping scheme).
One cannot always simply change one comment into an answer since it may be the combination of comments that answers the question. Also, upvoting these answers would be too cheap a way to earn reputation. (I deliberately choose to answer in a comment when I think my answer is essentially trivial.)
Is it easy to create some way to generate (upon request) a dummy answer ''answered through comments'' that doesn't generate reputation but ensures that the activity lists and the users realize that the question is actually answered?
This wouldn't prevent others to write additional answers if they think the question hasn't been satisfactorily treated.
