I am glad it works for some, and sorry it doesn’t for other. But i am not maintaining it for several reason:
1. i now use emacs cvs
2. wordpress is only working via TOR for me which i won’t bother to setup with emacs
3. wordpress is not always working even with firefox and TOR (i sometimes get misterious error)

however when setting up
via (weblogger-setup-weblog), I obtain an error which is to long to attach it here it start with
Debugger entered–Lisp error: (error “Selecting deleted or non-existent buffer”)
set-buffer(” *URL*”)
(save-excursion (set-buffer xml-buffer) (when (fboundp …) (url-uncompress)) (goto-char (point-min)) (search-forward-regexp “<\\?xml” nil t) (move-to-column 0) (let* (… …) result))

of course I downloaded xml-rpc.el!

I tried to contact both authors via email so far without success
if somebody could give me a hint, I would be grateful

thanks
