To reopen a closed question, one (1), three (3), orup to five (5) people✝ with the ability to cast reopen votes must agree that the question is suitable for the site and cast votes to reopen the question.
But:
- How does one actually vote to reopen? Is there a reputation level which you must have before you can see this function? Or do I just leave a comment along the lines of, "I vote to reopen"?
- What happens if someone without the ability to cast a reopen vote leaves a comment that they wish to vote to reopen?
- How can one draw attention to their closed questions? Is it done via a posting a new question? Or do you edit the closed question?
