Introduction to Post Groups
Post Groups provide a way to create a collection of Posts across your org chart. You can think of them as teams. Once created, Post Groups are used in the following features:
Knowledge Items - use Post Groups to assign Knowledge Items using Responsible Posts.
Notifications - use Post Groups to determine who should or should not receive certain Notifications.
Filter Views - use Post Groups in Knowledge and Objectives to quickly find what you are looking for.
