Clarification: This question did not promote any change, as did @Machavity's question posted eight months ago. That post received an "answer" approving the feature request. My question sought no feature request. This question was answered by Catija, with a link to the belated "status completed designation for a question posted 8 months ago.
So I fail to see how my question is a duplicate of that question.
(Start of my original question):
I searched meta.se, and the most recent policy I found which allows for repeated delete votes on the same question, I found here.
However, on math.se, three users, including me, received a pop up message when voting to delete a question that was undeleted:
You already voted to delete, and cannot vote to delete again.
This message was given to each of three of us, only after the question had been undeleted. One of us may have voted to delete again, but three of us tried and to cast a delete vote, but were prohibited from doing so.
This is the math.se question of interest.. Mainly I'd like to ask if users now are only allowed one chance to vote to delete, or not. If not, I am trying to understand what happened on this math.se post; is it possible that a CM intervened, that might have curtailed deletions? (Note: the time-line gives no information indicating action from a mod or a CM).
Later edit: Please see that a March, 2001 Feature Request was just now designated status-completed, as per Felippe Rangel.
