Click OK and your posting appears on your blog. The first time you post, a wizard will walk you through the process of entering your blog's URL, your username, and your password.
Type in a title and a posting, and click Publish on the Blog Post tab of the Ruler. Word opens a document with a placeholder title, a horizontal line, and an empty space for typing your blog post. From Word's File menu, choose New, then select Blog Post from the gallery of document types.
Word 2010 includes a feature that lets you post to a blog directly from Word's editing screen.
