There are several inheritance rules you should take into account before setting up the permissions:

* **Categories** inherit permissions from the component level permissions;
* **Contests** inherit permissions from the component level permissions;
* **Entries** inherit permissions from the contest level permissions. This allows you to setup unique permissions for the specific contest.
