Questions tagged [specific-question]

Please use this tag when you want to draw attention to a specific question on the main site. For example, if you want to draw high-rep users to close/reopen/edit a question, if you want to discuss the necessity of locking/protecting a question, etc. Do not use if your intention is to discuss/ask about a general issue, and you merely use questions as examples.
