Why are some questions closed?
Questions that need additional work or that are not a good fit for this site may be closed by experienced community members. Closed questions cannot be answered, but can be edited to make them eligible for reopening. If your question is closed, you will receive private feedback on the reason why it was closed.
Any closed question that receives one reopen vote by a user with sufficient reputation is automatically added to a reopen queue for community review. In addition, any question with significant edits that address the close reason(s) gets added to the reopen queue. If enough community members agree, the question will be reopened and can accept answers.
The categories of questions that may be closed by community members with the close/reopen votes privilege are listed below. The quoted text below each entry reflects the guidance shown to close voters when voting to close a question.
(Users with the flag posts privilege are also shown (largely) the same list if they attempt to flag a question and select "needs improvement". If you have the close/reopen votes privilege, attempting to flag a question using one of the reasons below will cast a close vote rather than a flag.)
Duplicate - The fundamental goal of closing duplicate questions is to help people find the right answer by getting all of those answers in one place. There’s more information in our help center article about duplicate questions.
This question has been asked before and already has an answer.
A community-specific reason (previously known as Off-topic) - Each community decides which specific topics are and are not allowed on their site. You can see this list of disallowed subjects for this site by viewing this help center article, or consult this site's Meta for specific guidance).
This question doesn’t meet a Sustainable Living Stack Exchange guideline.
If you believe the question can be reworded to fit within the scope, consider editing the question or leaving comments for improvement.
Note: If you choose this close reason, you will be shown another set of options (which vary by site):
If any community-specific custom close reasons have been added by the site moderators, they will be the first options listed here.
This question does not appear to be about sustainable living, within the scope defined in the help center. - If no custom close reasons are active for the site, this will be displayed as the first option instead.
This question belongs on another site in the Stack Exchange network - Sometimes, a question is not allowed on the current site, but would be allowed on a different site. In that case, a user can vote for the question to be migrated to another site.
If this option is selected, the user is then shown a list of sites that the question can be migrated to. The site's Meta appears in this list by default; if any other migration paths have been added by staff, they will appear here as well. (Site moderators also have the option to migrate the post to any site.)
Other - add a comment - Sometimes, none of the existing close reasons sufficiently describe why a question should be closed. In those cases, users with the close/reopen votes privilege can choose this option to specify a custom reason why they are voting to close the post, which will also be publicly displayed as a comment on the question. Once this option is selected, a text box appears below it, initially filled in with: "I’m voting to close this question because " (prompting the user to fill in the rest).
(Note: This option will not be shown in the flagging dialog to users without the close/reopen votes privilege.)
Needs details or clarity - Sometimes we need more information in order to help solve your problem.
This question should include more details and clarify the problem.
Edit your post to be more specific about what you're looking for, and be sure to address any concerns that other users brought up in the comments.
Needs more focus - If your question has many valid answers (but no way to determine which, if any, are correct), then it probably needs to be more focused to be successful in our format.
This question currently includes multiple questions in one. It should focus on one problem only.
This can often be fixed by breaking the post into multiple questions, or by focusing on a specific part of the problem.
Opinion-based - Discussions focused on diverse opinions can be great, but they just don't fit our format well.
This question is likely to be answered with opinions rather than facts and citations. It should be updated so it will lead to fact-based answers.
It’s often possible to rewrite opinion-based questions to focus on a more fact-based line of questioning. If you see a way to do this, consider editing the question.
Who can close questions?
Users with 500 reputation can cast up to 24 close votes per day. When a question reaches 3 close votes, it is marked as being
Closed, and will no longer accept answers. Users with the same privilege may also vote to reopen questions the same way. Each user may only vote to close and reopen a given question once. (For example, if you vote to close a question that is closed and then later reopened, you cannot vote to close it again.)
Moderators may close or reopen any question with a single vote, without any of the restrictions mentioned above.
