Testing the math delimiters: $$\int_{-\infty}^{\infty}e^{-x^2} \, dx= \sqrt{\pi}.$$ Success! We appear to have MathJax on the blog now. This will obviously greatly facilitate the posting of tutorials, or any discussion at all concerning math, as $\LaTeX$ is (mostly) available.

Testing: $A \; \x{implies} \; B$. This means that my new command of \x{} is equivalent to \text{}, and works just fine.
