<p>I'm not sure I follow. I've pasted that TeX below and it's rendering (albeit slowly) in the preview. </p>

<p>\begin{align*}
    -N-\frac{1}{N}\sum_{j=1}^N (2j-1) \left(\ln\left(\frac{1}{2}+\int_{\bar{x}}^{x_j}
\exp\left(-\frac{(t-\bar{x})^2}{2s^2}\right)\mathrm{dt}\right) \
+\ln\left(\frac{1}{2}-\int_{\bar{x}}^{x_{N-j+1}}
\exp\left(-\frac{(t-\bar{x})^2}{2s^2}\right)\mathrm{dt}\right)\right)
\end{align*}</p>

<p>EDIT: Probably the place to ask is the <a href="http://groups.google.com/group/mathjax-users/" rel="nofollow">MathJaX Users Group</a>. Something like this has <a href="http://groups.google.com/group/mathjax-users/" rel="nofollow">already been asked</a> I guess that suggests one find another way of doing it (which you have already done and it is far more readable in my opinion). </p>
