Contribute Access- Determines which users cancreate, edit, or publisharticles.
Can Be Based on Multiple Factors

Departments
Locations
Flexible & Scalable
Instead of manually assigning permissionsarticle-by-article, User Criteriaapplies rules to the entire Knowledge Base.
This method provides acentralized way to manage permissionsfor large teams.
