The writing settings controls features that affect writing new posts. These settings control WordPress’s features in the adding and editing posts and pages and things like post via email and Update Services.
Editing the writing settings
You can use these checkboxes to control some of your blog’s formatting.
Convert emoticons such as 🙂 and 😛 to graphics on display – Checking this tells WordPress to convert all of the emoticons in your posts into graphical smilies.
WordPress should correct invalidly nested XHTML automatically – Checking this helps make sure that what you write in your posts is valid XHTML code. You should probably check this box since invalid code sometimes causes problems with web browsers.
Default post category
The category you select from this dropdown is called the default post category. The default post category is the category assigned to a post if you fail to assign any other categories with writing your posts. If you delete a category, the posts in that category will be assigned the default post category.
Default post format
The Post Format you select from this dropdown is called the default Post Format. Post formats are used by themes to create different styling for different types of posts. This setting is only visible if the current activated theme supports post formats. The WordPress Twenty Sixteen theme is an example of a theme that supports various post formats including Standard (no special format), Aside, and Gallery.
Press This is a bookmarklet: a little app that runs in your browser and lets you grab bits of the web and easily post it to your blog.
Use Press This to clip text, images and videos from any web page. Then edit and add more straight from Press This before you save or publish it in a post on your site.
Drag-and-drop the following link to your bookmarks bar or right-click it and add it to your favorites for a posting shortcut.
Post via email
With this option, you can set up your blog to publish emails as blog posts. To do this, you would send an email to a specific address you’ve established for the purpose. More than likely, you will need the help of your web host and/or your email provider. This feature is 100% optional; you can still publish posts from the Posts Add New Screen if you don’t want to post via email.
Complete the following fields to post by email:
Mail Server – A mail server receives emails on your behalf and stores them for retrieval. Your mail server will have a URI address, such as mail.example.com, which you should enter here.
Port – Servers usually use port 110 to receive requests related to emails. If your mail server uses a different port, enter that port number here.
Login Name – If, for example, the email address that you will be using for the writing by email feature is firstname.lastname@example.org, then ‘wordpress’ is the Login name.
Password – Enter the password for the above email address here. Three possible passwords are displayed by WordPress in the introduction section of this screen.
Default Mail Category – WordPress will assign this category to all of the posts published via the post by email feature.
When you publish a new post, WordPress automatically notifies the update services of the sites listed in the box. For more about this, see Update Services on the Codex. When entering services, separate multiple URLs with line breaks. If your Privacy Settings Blog Visibility is set to “I would like to block search engines, but allow normal visitors”, the message “WordPress is not notifying any Update Services because of your blog’s privacy settings” is displayed.
When you have finished making changes click Save Changes.
