Adding MathJax
Fragment of a discussion from Support/LiquidThreads
Sorry, I was not following this thread and I thought you'd comment on the MathJax issue tracker. As indicated there, Peter gave you commit access to the following repository:
https://github.com/mathjax/MathJax-i18n
which contains localization data that should be supported by TranslateWiki:
https://github.com/mathjax/MathJax-i18n/tree/master/JSON
(the only thing I was not sure is about the new lines "\n", but I was told it is not a problem)
The repository contains Python scripts to convert to/from the MathJax format.
