Avanimisra,

Thanks a lot, I did not knew this blog, it is a remarkable and useful of wordpress. It is very close to what I was imagining for my own purposes.

I have a couple of questions :

1) Indexation of information in tao's blog seems to rely mainly over categories. Categories are a nice indexation way, but could be nicely completed through an arborescent like indexation.

For instance, I would like to have

http://www.myblog.org with some classical posts and archives, but would also include

http://www.myblog.org/math, that would also have its own post and archives, that would also includes

http://www.myblog.org/math/pde

http://www.myblog.org/math/stochastic

etc...Is that easy to achieve using wordpress ?

2) I did not knew that Latex was wordpress compatible. Thanks very much. Latex can be used also in comments ?

thanks again for these informations
