I find here that MathJax supports only math-mode macros (such as \sqrt{}) and not text-mode macros (such as \begin{align}). I am currently building a small wiki that will host mathematics articles, and so expect that both kinds of macros will be desirable. The page linked above recommends a TeX to HTML converter, but (unless I'm misunderstanding) these all seem to be alternatives to MathJax.
What is a good solution to get the attractive rendering of mathematical symbols (as in MathJax) combined with the standard text-mode alignment environments found in LaTeX?
