I have  tried setting up Live Writer 2012 to go against the blog section of my Orchard site.  I followed the guidance in: http://docs.orchardproject.net/Documentation/Blogging-with-LiveWriter.  However, there is a gap and I'm falling through.

LiveWriter asks - "what blog type?".  I answer "Metaweblog API" as the best guess.  It returns: http://<hostname>/<mw-script>.  I don't know what to put here.  Experiements all failed.  I don't know what the needed XMLRPC endpoint is.  I have enabled XMLRPC and Remote Blog Publishing. 

One issue, my site is more than just a blog so the blog root is at mysite.com/blog, not mysite.com.  That shouldn't be a problem.

Any thoughts Orchard world?

The url is http://yoursite.com/XmlRpc

Thanks.  Worked perfectly.  I'll look into updating the documentation to make this info explicit.
