I have followed the instructions found here and here. Also:
Here is an image of my attempt to add the blog.
Windows Live Writer says it "was not able to automatically detect your blog settings." So, I try to do it manually as follows.
Windows Live Writer says, "Invalid Server Response - The response to the blogger.getUsersBlogs method received from the blog server was invalid."
I have already setup Remote Blog Publishing and XmlRpc as follows.
Is there anything else that I need to do? For instance, when Windows Live Writer asked for the "Remote posting web address for your blog," it has a template like this:
http://<hostname>/<mw-script>
That I fill in like this:
http://www.muddlingthru.com/we-re-all-just-muddling-thru
I suspect I might have the incorrect remote posting web address.
The blog account must be the url of your blog, not of a blog post. It will then detect special metas that indicates the /XmlRpc url that implements MetaWeblog API.
You can also configure it manually choosing Metaweblog provider.
