Adding a blog post is very similar to adding a page. “Posts” is directly under the “Dashboard” tab in the left navigation menu in the WP-admin.
The most noticeable difference between the two is that the “Add a New Post” page will have “Categories” and “Tags” in the right hand widget area.
If you ever post a post and find it doesn’t show up in your blog…check to see you didn’t create a page.
As far as the Content Editor goes it is exactly the same as it is in the “Add a New Page” page. Just about anything you can do on a page you can do in a post.
The post is organized by its category and tags and can be found by either while the page needs to be on a menu or hard linked in a widget.
