Discussion Namespaces (categories) turn a flat list of posts into an organized forum. Instead of scrolling through everything, members can filter by “Announcements”, “Questions”, “Ideas”, or whatever categories make sense for your organization. Discussion category settings page

That's it

Categories are now available in all groups across the organization. When members create posts, they can select a category. When browsing, they can filter by category.

​
Key details

  • Categories are organization-wide — the same set is available in all groups
  • Only administrators can create, edit, reorder, or delete categories
  • Categorizing posts is optional — members can post without selecting a category
  • Editing a category name updates it everywhere — all existing posts with that category
  • Deleting a category removes the tag from existing posts but the posts remain

​
Common scenarios

Categories are optional by design, so members may skip them. Lead by example — make sure admins always categorize their posts. Consider adding a gentle reminder in the post creation flow. If categories aren’t adding value, you might have too many or they might not match how your community actually discusses.
Namespaces are organization-wide — the same categories appear everywhere. This is by design for consistency. If a group doesn’t use certain categories, members simply don’t select them. The filter only shows categories that have posts in the current group.
5-10 for most organizations. Fewer than 5 and categories aren’t adding much. More than 10 and members can’t decide where their post belongs. Think broad themes, not specific topics.
Not natively — any member who can post in a group can use any category. To restrict posting, use the group-level “Only admins can post” setting and direct regular member discussion to a different group. For example, “Announcements” category in the Main Group works when only admins can post there.
