As one possible step in Cleaning the Archives there is a suggestion on closing old unanswered questions. By definition, an unanswered question is
- A question which doesn't have any answers
- A question with no upvoted answers
By old question, we will define that as a question older than three months, and where the poster of the question hasn't been seen in three months. Either, users with enough reputation could cast a close vote and users without could flag the question with the same reason:
This question appears to be off-topic because it is older than three months, the poster of the question hasn't been seen for three months and it contains no answers or no upvoted answers.
If the original poster (OP) of the question returns, and want to have the question reopened - it will be reopened if it's closed for the reasons mentioned above.
If you agree with this suggestion, upvote this question, if you disagree, downvote the question. Adding answers and suggestions are most welcome.
