I'm pretty new to MathJax, and one way I've been trying to learn is to click on "edit" for posts that use features I would like to learn. Then I just click "cancel." The last time I did this, I got a notice that my previous edit was rejected. The last time I intentionally edited a question, I know it was accepted, because I got 2 points or something like that, so I know this is something else.
Am I violating some rule, or did I just forget to click "Cancel"?
