How to add and edit posts in WordPress
Posts, referred to as articles, can be added and edited from the admin panel. After you have logged in, click on the Posts menu which is shown on the left.
You will find existing posts and columns showing information related to the post (e.g. title, author, category, etc.).
To hide/display columns, click on the Screen Options button in the upper right corner and mark/unmark the respective check boxes.
You can also mass edit posts. Mark the checkbox next to the title of each post that you want to edit,
select Edit from the Bulk Actions drop-down then click on the Apply button next to the drop-down menu.
Select options that can be used to assign posts to a category or categories.
You can change the author, status, and format of the posts, enable or disable comments and pingbacks, and make the posts sticky on the frontend.
Make sure you click the Update button after making changes.
