When I'm checking 'Applications < Site Settings', I saw Stack Alert which redirects me to this page, but that page is not found. If I may ask, can this be removed?
@XanderHenderson I want to write the question I asked earlier here. And I want to show you how I changed the numbers. And I will post the question to MSE. I want to get approval.
I can't really give you "approval" ahead of time. I have already told you that (1) I think contest problems are generally a bad fit for Math SE and (2) I don't think that proof verification questions are of much use.
You have solicited an opinion. The given opinion is "don't post it". But you are free to do what you will.
