Publishing vs Drafts

You can write on a post or page as a draft until you’re happy with it, then you can publish to the world, make it password-protected, or make it private (it would be available only to you and your blog readers that have editing or administration privileges). Blogs can also be available for only those enrolled in a course.

After publishing a page or post, you cancontinue to edit a post or page’s content – WordPress will save the drafts while your published content is still available for viewing.

WordPress also has versioning control, so in case you need to go back to a previous edit, you can.
