Please excuse if this a moderator newbie question but, is there a way to ask someone why they deleted their own question?
I provided an answer to Windows Phone 7 UserExtendedProperties today. After revising the answer to give the asker all the info they needed they added a comment to say the answer was what they needed and then they promptly deleted the question.
Surely if it's a good answer it's worth saving the question and answer for the future benefit of others.
How do we inform people that this is not how the system is supposed to work?
I've previously (before getting moderator tool access) noticed questions with multiple useful answers suddenly disappear. (So I don't think this is an isolated case.) Surely for the sake of preserving answers which may be useful to others there needs to be a way to discourage deleting things which may be useful to others.
