Instead of writing your blog posts online, then you may prefer to write the offline and not post them until you are ready to publish.
To do this it is possible to use Word. You find a description from Microsoft on how to do it here:
When you setup your account, then you must select Telligent Community as the blog provider.
Insert your <blog url> + /metablog as the Blog Post URL like: https://dynamicsuser.net/nav/b/admin/metablog
The enter your DUG username and password.
