Is there a place where I can create posts where I can test out MathJax / $\LaTeX$ support? I've seen this Q/A on how to use MathJax / $\LaTeX$ but I would like to experiment with it and have others get information or provide insights on my attempts.
Note that answers don't have titles, but you can use small $\TeX$ formulas in titles as well. Try and use them sparingly though, as $\TeX$ will slow down rendering of question titles.
