Since I’m a little bit lazy and I really prefer Emacs as text editor I was looking for an easy solution to publish my blog entries out of Emacs. My entry to search for a solution was the blog of Sacha Chua. She uses EMACS as well and had done some improvements in the directions of simplify the workflow with org-mode. In an old blog entry I found the solution to my needs.
The next step was the installation of org2blog and xml-rpc since this two tools are needed to get the automatism to work.
After that I only have to configure my ~./emacs like this:
(require 'org2blog-autoloads)
(setq org2blog/wp-blog-alist
'(("wordpress"
:url "http://btd67.com/xmlrpc.php"
:username "btd67"
:tags-as-categories t)))
