@AsafKaragila thanks for that math.stackexchange.com/questions/3258571 I was aware I could do it but was hoping to give the OP a chance to do so themselves

...to repair the situation

@user334732 I had a conversation with Jyrki to smooth things through. He was going to do it, but there was a lull, and I ended up doing it myself before he had the chance. I agree that it would have been better for him to have done it, but ultimately it's about preserving content.

@AsafKaragila ok thanks. I understand his frustration. He previously deleted some great content upon realising the question was mine - before I could digest it properly. I find it really sad but it is what it is I guess.
