I can't seem to find anything in the RM for this. I can't imagine there's a huge demand by forum goers wanting to embed math into their posts, but I'm one that does. Here's a CDN based system that can be used to embed math into web pages. http://docs.mathjax.org/en/latest/start.html And here's a description of LaTeX. https://en.wikibooks.org/wiki/LaTeX/Mathematics I imagine that a BB Code would replace the LaTeX delimiter with [math][/math] or [latex][/latex] type codes. Anyway, just putting it out there that there seems to be a lack of an add-on/BB Code of this type. Maybe someone looking to practice some coding might be interested in a project like this?
