Before actually publishing your post to your WordPress blog, you can tweak a couple of settings. You can…

schedule your post, or publish it right away.
set the status to Draft or Published.
attach tags and categories to your posts.
Note: If you have used Ulysses keywords with your sheets, they will automatically be added as categories and tags as long as they correspond to categories and tags already in use on your WordPress blog. Also, you can choose from tags and categories already in use on your blog (on Mac, follow the ...)
add a featured image or an excerpt to your post.
define the slug. That’s the URL of your blog post, essentially.
Note: If you don’t define it, the slug will be derived from your post’s title.
set a title link for your post. You can also create a title link directly during writing: Ulysses will automatically use any link you set on the first header as a title link.
Note: You can only take advantage of title links if you installed a dedicated WordPress plugin, e.g., this one).
decide what should happen after you push the Publish button (Action): You can either open a preview of the post in the browser or open the WordPress backend for editing.
Note: If you choose “None”, your post will be uploaded to your blog, but you will stay in Ulysses.
