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.

Choose a Name for the Group
Use name when displaying in a knowledge item - When checked, the name of the Post group will be displayed in the Knowledge item
Sequence - This is a number which determines how the Post group is sorted. Lower numbers are sorted first. Same numbers are sorted alphabetically. Leave blank to sort last.
Global - A global post group shows up everywhere. A non global post group only shows up under Knowledge Responsible Posts.
