PublishPress allows you to choose “No Author” for some WordPress posts. By default, WordPress requires an author for every post, but sometimes this isn’t ideal.
Here are two use cases for “No Author”:
- You can choose “No Author” to show that a post is waiting to be assigned to someone.
- You can choose “No Author” to show that a post has been written anonymously.
