A mathSE query posted by someone received interesting info in an answer by someone else. I have bookmarked this query. Since it has been closed, I have also downloaded the (full) html page, just to be safe, in case the query is deleted.
For the next time that such a situation occurs, I am wondering whether such a precaution is needed. Can I prevent a query that has been closed from being deleted? Assuming not, is it possible to request that if the query is going to be deleted, that before it is deleted, I receive notification, either by email or a mathSE message, so that I can then download the query, just before it is deleted.
Finally, assuming that none of the above is feasible, and assuming that I keep a specific record of the query's title and the url that was assigned to it, what precisely does it mean for a query to be deleted? Does that mean that it's immediately gone for good? Can I recover a deleted query just for the purposes of downloading it to my hard drive? Is there a transition period, after the query is deleted where it is not yet gone for good?
Although I have included the feature-request tag, the primary intent of this query is to better understand the intricacies of mathSE's delete-query process. If a feature can be added to address my concern, great; but at this point all I'm asking for is to understand the process.
Responding to the comments so far.
The question that I safeguarded is this problem. In fact, the reason that I safeguarded this problem was because of the information in Will Jagy's answer + his subsequent comments.
I have already saved the corresponding webpage for this specific question to my hard drive, so this particular question is not an issue.
Also, I wasn't intending to use mathMetaSE in general for such requests. This meta question is a one time only request for general information, not pertaining to any specific question, currently deleted or closed.
In fact, I think one of amWhy's comments has completely resolved the issue, given that I will soon be at a 10k+ rep. I have no interest in undeleting any already deleted query, or requesting such a deletion. My only concern is whether I can still privately access such a question simply to re-examine the information on it.
According to amWhy's comment, all I have to do, once I reach 10+k rep is to review the help articles or perhaps meta queries for documentation on how to (privately) examine a deleted question.
