Re: [O] question about org2blog and latex

[Stephen J. Barr]

Thanks for the help. I just checked the variables and
org2blog/wp-use-wp-latex was set, but the wp-latex plugin was not
installed :) All is working now, although it is definitely a little
grainy. But, it'll certainly lead to an awesome series of blog posts
nonetheless. Puneeth, thank you so much for the fantastic plugin.

One other quick question: Does org-mode and org2blog work with
numbered equations and equation references? If so, could someone
provide a simple example?

Thanks,
Stephen
