This is a workaround answer, but it works for me; Since MathJax (LaTeX) preview does work on questions and answers, for comments, I'd usually just force my own preview by temporarily abusing any existing post (say, by going to edit the question) then copy-pasting my MathJax when I'm happy with it into my comment and abandoning the edit. Sometimes, I'd also ...

Here we do not have the notation plugin that Chemistry has, but you can use the normal MathJax notation which should be sufficient for most things you may need to write out as formulae on Space.SE. Because there is overhead at server end, sites don't generally get more complex plugins unless absolutely needed, and Space doesn't have a burning need for ...

Subscripts can be written in the format $_n$. For example, H$_2$O becomes H$_2$O. Superscripts can be written in the format $^n$. For example, Na$^+$ becomes Na$^+$. Values longer than one character should be enclosed in curly brackets {}. For example, Ca$^{2+}$ becomes Ca$^{2+}$. Chemical formulas frequently-used in Space.SE, ready to cut-and-paste. ...

There's a formatting sandbox on the mother meta, and one for MathJax specifically on Math. (There are a few other sandboxes, no doubt, but not of any particular relevance.)

Only you will see your own drafts as you return to that same page where it was saved. It will do that from then on automatically. I'm not sure exactly what triggers ...

Yes. If you upload the image using the image dialog so it's hosted by imgur, you can change the name of the image to display resized ones that are automatically generated on upload: Add l at the end of the image name for a 640 pixels in width large image, add m for a 320 pixels wide medium image, t for a 160 pixels wide tiny image, or s for a small 90x90 ...
