There's an official Discourse plugin (link below) that would allow for users to post LaTeX style equations and have them rendered. As far as I can tell, this plugin is not enabled on this Discourse (test: $x^2$ ). Would have made [my first post](https://racket.discourse.group/t/plotting-a-lambda-that-returns-a-math-matrix-vector/1365) look a bit cleaner. For example this `$\mathbf{N}^p(\xi) = [N_0^p(\xi), N_1^p(\xi), \dots, N_p^p(\xi)]^T$` would have rendered as ![image](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/b3c71ff61ddd9c11a81941d063beae337570fbe2.png) but nicer (e.g., no background, same size as text). I would have uploaded the equations as images, as I've done on this post, but as a new user I could only upload a single image. > **[Discourse Math](https://meta.discourse.org/t/discourse-math/65770)** > > :discourse2: Summary Discourse Math uses MathJax (default) or KaTeX to render maths in your Discourse forum. ๐Ÿ›  Repository Link https://github.com/discourse/discourse-math ๐Ÿ“– Install Guide How to install plugins in Discourse Features You... ---

@spdegabrielle This sounds like a good idea. ---

Good idea. Turns out this is a standard, "supported" plugin for discourse, so I've enabled. it. There were several options that I could select, and I have no particular opinion about any of them. Here's a screenshot, in case anyone thinks that these other options should be enabled. ![Screen Shot 2022-10-11 at 10.51.19 AM](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/a8c1fdf77b4e43214a23063e0d4a2debad310c34.png) ---

Hmm... maybe it wasn't enabled? ---

yay! okay it works. Looks like double-dollars have to include line-breaks. ---

I understand most people use the web interface (or at least read mail as HTML), and might feel differently about more structured posting, but even the [quote] etc... markup causes my eyes to glaze over and my fingers to consider unsubscribing.

I'm not sure precisely what "accessibility features" would be, but I'm in favor of enabling them given the option. ---

The "accessibility features" enable this MathJax extension (which normally is in one of the menus, I believe): [https://docs.mathjax.org/en/latest/basic/a11y-extensions.html#a11y-extensions](https://docs.mathjax.org/en/latest/basic/a11y-extensions.html#a11y-extensions) ---

I skimmed it, but didn't read carefully to see why it might not always be on. Is there some reason that this is not on by default? Maybe we should just turn it on and see what happens?
