This post is being written using Windows Live Writer, which is great! I had to add minimal support for the MetaWeblog API to pblog because the beta version of Windows Live Writer (here’s the SDK) does not yet allow you to add new providers so I couldn’t add supprot for pblog’s Web Services-based publishing protocol. My apologies for any problems you may have had while I was upgrading the server and any problems that may appear in the future given that I still have to add support for images and also after-posting editing functionality.
Support for the MetaWeblog API also means I can post from Word 2007 as well.
