# Require topics in stream messages {!admin-only.md!} 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](/help/configure-message-editing-and-deletion) is enabled, any other user can then edit the topic of messages without a topic to set a topic, regardless of the value of the [topic editing policy](/help/configure-who-can-edit-topics). You can instead choose to require a topic for new stream messages. ### Require topics in stream messages {start_tabs} {settings_tab|organization-settings} 2.
