 Various self-explanatory options are available to configure a team, to manage invites and membership, visibility of the team, allowance of other team membership and password protection.
 
+**Prevent teams from being a member of another team**
+
+When this option is enabled, the team can no longer be directly added as a member of another team. However, this restriction only applies to new direct additions. Existing memberships are kept, and inherited memberships are still possible if this team belongs to a parent team that gets added elsewhere.
