Add media: Add images, videos, audio and other media from files on your computer, URL or Media Library.
Post Editing Area: Enter your writing, links, images, videos and any information you want to display.
Kitchen Sink: Click here to reveal additional formatting tools.
Format: Make sure you are in “Visual” view to write. "HTML" view is for entering code - usually embedding a video for the typical user.
Post Tags (optional): Insert words and phrases describing the blog post. Posts with similar tags are linked together when a user clicks one of the tags.
Categories (optional): One of the best organizational tools Wordpress has to offer. Create general topics that the post can be classified in. Readers can later browse categories to see a specific set of posts.
Save Draft: Allows you to save your post as a draft rather than immediately publishing it. (While Word now has autosave functionality, it never hurts to be extra safe.)
Screen Options: Expands a top menu that allows you hide/show different options. Sometimes a plugin that has post-specific functionality hides in this area.
