Only allow admins to create new streams
Note: This feature can only be controlled by organization administrators.
By default, any user can create new streams. You can enable a setting that only allows administrators to create new streams in the organization.
From your desktop, click on the gear () in the upper right corner.
Select Manage organization.
On the left, click Organization permissions.
Select the Prevent users from creating streams checkbox under the Streams & custom emoji section.
Type a number in the Waiting period for stream creation (in days) input to specify the period of time users must wait to create a new stream.
Click on the Save changes button to save any changes you made to your organization settings.
