Require topics in stream messages

By default, users are not required to specify a topic in stream messages; if a user sends a message without a topic, the message's topic is displayed as (no topic).

If message editing is enabled, any other user can then edit the topic of such a message to set a topic, even if community topic editing is otherwise off.

You can instead choose to require a topic for new stream messages.

1. Go to Organization settings.

2. Under Message feed, select Require topics in messages to streams.

3. Click Save changes.
