Big thanks to Jeff Julian for his guidance on how to setup Word 2007 for blogging. As proof of the success I’m blogging from Word for this article!
Jeff points out that for Geekswithblogs.net members, the Metablog API service URL is located at http://www.geekswithblogs.net/[YOUR USER NAME]/services/metablogapi.aspx
so set this up with ‘Other’.
Thanks Jeff!
