Stop using Mimetex and replace it with a more modern Latex solution

Hey, Bo

Two errors I've noticed.

First of all. I cannot stack equations:

Code:

$$
some math\\
some math\\
some math\\
$$

Will render as one line rather than stacking like it does with tex. I know mathjax has a way to do this. Am I missing something in how this works?

Aren't you supposed to use array or align environment?
\[
\begin{align*}
a &= b\\
ab &= cd\\
abc &= def
\end{align*}
\]

Code:

$$
\begin{align*}
a &= b\\
ab &= cd\\
abc &= def
\end{align*}
$$

The quick edit has no preview, hence you editing the source, or am I missing something?

Oh okay, so it's a much better mathjax than mathoverflow; mathoverflow runs the command:

Code:

$$
a=b\\
c=d\\
$$

as an automatic align. That's fine, I just assumed it'd be the same as math overflow.

As to my second point. If you do a quick edit; and save the edit; all the mathjax commands revert to text when you confirm the edit. For instance, I'll write an equation and then quick edit it and save it:

\[
e^z
\]

EDIT: after the quick edit; you can see all the mathjax code reverts. Not a big deal; just have to use full edit exclusively with these commands.
