Suppose there's a question over on MathSE under the tag [puzzle] that, among all questions tagged puzzle, I think would especially be of interest to the users here on PuzzlingSE. Also, it's a question I really want answered :P. Is there an appropriate way to bring this question to the attention of PuzzlingSE users?
One idea would be to cross-post the question, but I think there's a general agreement that duplicates should be avoided across SE sites for the sake of good housekeeping (can't mark-as-duplicate across sites).
I could bring it up in chat, in The Sphinx's Lair I presume (great name btw), but then I don't think that would reach a very wide audience.
Does anyone have any appropriate suggestions?
