The question How to destroy a CD/DVD rom safely? already has good answers on the sister site Super User Stack Exchange, but I think it belongs on this site. If the question didn't exist there already, I'd ask it here.
What should I do in this case? Should I ask the SuperUser admins to migrate the question? Should I ask the question here and answer it with a link and a short summary of the answer given there? Is there instead some other administrative action you can take? Thank you in advance for the help.
By the way, could we just check the list of their questions with the [security] tag and steal all the good ones, or at least all the ones that are also approperiate here?
Update: I have not have made this my goal clear in the question. If someone searches "destroy cd" in the search box of Information Security SE, he doesn't currently find a relevant question. I'd like the answer for that question searchable, because it's a good question that can occur to others too. Please answer this meta question in a way that tells how to make it possible to make that and similar questions searchable.
