I have seen that there are so many questions that has acceptable answers without the OP has not accepted. I have seen this issue has addressed to a certain extent in some questions. Yet, it is about unanswered questions.
So is there a way to notify users who have questions with no accepted answers to check their questions? If not (which I believe so), wouldn't it be better to implement a feature like that?
With that, they can either give their feedback or they can share if they have found an answer themselves. (this will help future users to get a certain or verified answer)
