This very detailed training video demonstrates everything you need to know about writing a post in WordPress. All of the basics are covered, as well as some of the more advanced features that are hidden below the surface.
WordPress pages are covered in a separate video. If you aren’t clear on the difference between posts and pages, this brief video explains posts types in more detail and provides guidance on when to use each type.
You might want to grab a cup of coffee before you start. This video runs a little over 27 minutes.
