Basically, I'm using Mathjax which will call external JS for each page load. The problem is that Xenforo is using ajax in a lot of places such as when you use the quick reply box and when you edit and preview a post. This means I won't be able to see the Latex rendering until I reload the page. It appears Mathjax has a solution for this. I'm trying to see if anyone is able to understand this method http://docs.mathjax.org/en/v1.1-latest/typeset.html Anyway we can allow post preview to load the JS?
