The other day I saw a recommendation from Eddymage on how to include special characters using MathJax. Like this:
$$ ^\dagger $$
I have no experience with MathJax, and wanted to experiment how that works. And for some reason, sometimes the preview that is rendered under posts looks different than what you get when you hit submit (I have that experience with tables sometimes, and it was the case here, too).
Rather than spamming the Meta or creating spurious posts on the main site, is there a test-bed post somewhere that can be used to play around with markdown and formatting, that is periodically purged of answers and comments?

since that won't require javascript to render (which becomes very noticeable if there's a lot of MathJax on a page). \$\endgroup\$
