<p>Latex support is now built-in. See this meta thread from math.SE: <a href="https://math.meta.stackexchange.com/questions/2/tex-math-markup-is-sorely-needed">https://math.meta.stackexchange.com/questions/2/tex-math-markup-is-sorely-needed</a></p>

<p>I have made this answer CW in case you want to see what you have to do to get latex output.</p>

<p>A demo: $\alpha$</p>

<p><strike><a href="https://math.meta.stackexchange.com/users/38/john-gietzen">John Gietzen</a> over at <a href="http://math.stackexchange.com">http://math.stackexchange.com</a> has created a greasemonkey script which uses the Google Charts API to create images on the fly from latex. I have asked his permission to adapt it for our site. See his answer to this question: <a href="https://math.meta.stackexchange.com/questions/2/tex-math-markup-is-sorely-needed">https://math.meta.stackexchange.com/questions/2/tex-math-markup-is-sorely-needed</a></p>

<p>Here is a demo of the script: $\alpha$</p>

<p>Ok, here is the script put together by John: <a href="http://userscripts.org/scripts/show/81977" rel="nofollow noreferrer">http://userscripts.org/scripts/show/81977</a></p>

<p>Presently, I have it working for in firefox with <a href="https://addons.mozilla.org/en-US/firefox/addon/748/" rel="nofollow noreferrer">greasemonkey</a> installed. Apparently, it works in Chrome as well but I have not been able to get it to work. I will update this answer if I can resolve that issue.</p>

<p>Perhaps, we should start using tex + the above script. The advantage is that as and when we get tex support from the devs all our posts will look nice.</strike></p>
