When you write a post that you want to publish but you don’t want it to show on the homepage you can use the category not on home.

- Click on “Write a post” on the sidebar of the homepage
- Write your post here and categorize it by checking the appropriate boxes and the box of the extra category “not on home”

Now you can save (and continue editing) or publish. If you publish this post you can find it in the categories you have checked but it will not be visible on the homepage. If you open one of the categories you will find your post.
