Since we have MathJax enabled, it might be a good idea to advertise that it is on and point to a primer on using. Amateur radio is so full of math, it's an important tool. I know my way around the SE network but didn't have a need to use MathJax until becoming active here and it's not a terribly obvious markup.
If there is a way to note that MathJax is on during the ask a question phase, that would be great and if there is a one primer to rule them all, we should link to it.
Thoughts?
