In relation to:
can I even see where, or if, I have, or might have, closed/deleted/etc. questions? The answers don't explain how or where information on the question was found.
Go to your profile.
Click the "questions" tab to see your list of questions.
Scroll to the bottom, and click "deleted recent questions".
There you should see the questions that have been deleted "recently". I believe the definition of "recently" here is "within the last 60 days".
