Posts are entries that display in reverse order on your home page. Posts usually have comments fields beneath them and are included in your site’s RSS feed.
To write a post:
Log in to your WordPress Administration Panel (Dashboard).
Click the ‘Posts’ tab. Click the ‘Add New’ sub-tab.
Start filling in the blanks: enter your post title in the upper field, and enter your post body content in the main post editing box below it.
As needed, select a category, add tags, and make other selections from the sections below the post.
When you are ready, click Publish.
