How can I add MathJax support? I would like to be able to render math formulas on my forum.

Here's what I've done so far:

I created a block in `block_head`

region with this content:

```
<script type='text/x-mathjax-config'>
MathJax.Hub.Config({
tex2jax: {inlineMath: [['$', '$'], ['\\(','\\)']]}
});
</script>
<script src='http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML' type='text/javascript'>
</script>
```

So now the formulas render when I open a post:

But not when I look at all the posts I created in the profile

And, more importantly, not during the preview

Is there a way to force-render mathjax?
