Restrict stream creation

By default, anyone other than guests can create new streams. However, you can restrict stream creation to

• Organization administrators, or
• Organization administrators, and members with accounts at least N days old, for any N.

For corporations and other entities with controlled access, we highly recommend keeping stream creation open. A typical Zulip organization with heavy use has as many streams as users.

For large Zulips where anyone can join, we recommend restricting stream creation to those with accounts at least a few days old (we suggest starting with N = 3), to make it easier to cope with spammers and confused users.

1. Go to Organization permissions.

2. Under Other permissions, configure Who can create streams.

3. Click Save changes.
