Ok, here's how this works: https://legacy-www.math.harvard.edu/texman/ is the default guide for all sites that have MathJax enabled. It's pretty generic, and that's a good thing. Any site with ...

Chemistry equation \ce modifier works in a non chem SE site's posts, but not in search results. Should we consider it "working" and start using it?

I'm not the foremost expert on this, but my understanding of MathJax is as such: It's entirely not loaded on some sites. This includes Meta Stack Exchange, which is why 'normal' maths such as $1 + 1 =...
