Thanks. I understood to a certain point, but not completely.
Go to the “Settings->User Role Editor->Additional Modules” and turn ON the “Activate “Create” capability for posts/pages/custom post types” option under “Content edit restrictions” subtitle. Do not forget to grant this capability to the roles who should can create posts.
I found the Create box in Content Edit and I clicked it and saved. I see where I can click “create posts” ability for users if I want.
publish_posts allows to publish posts. So revoke it from your role.
I don’t see where to revoke anything. Where is that option? thanks!
Revoke also (if granted) edit_others_posts, edit_published_posts, delete_posts.
