WordPress User Guide - Posts
Posts are the “blog” or news component of your WordPress website. They help you share timely information with your readers–upcoming events in your department or recent program news–that is likely to change rapidly or become dated more quickly than the content in Pages.
Posts flow into a long list on a single Page of your website, with the most recent Posts at the top; see the News page at the Sample UMaine Website for an example.
The Edit Posts screen displays a list of all your website’s posts. If your website has too many posts to display on one screen, you can more easily search for a post by title using the search box to the upper right:
From here you can edit, delete or view your posts simply by hovering over the page title. To edit a post’s contents, click on the post title, or click Edit.
