External blogs
From MoodleDocs
Location: My profile settings > Blogs > Register an external blog
In Moodle 2.0 onwards, you can register external blogs, such as Blogger or Wordpress so that entries are automatically included in your Moodle blog.
By default, the number of external blogs each user is allowed to link to their Moodle blog is 1. This may be changed by an administrator in Site administration > Appearance > Blog.
