-# Make an announcement
-
-An announcement on Zulip is a message which will reach
-all users in an organization.
-
-## The #announce stream
-
-The #announce stream is just like other streams in most ways, but it's
-conventionally used for organization-wide announcements.
-
-![Example message](/static/images/help/announce-message.png)
-
-By default, everybody is subscribed to this stream. For this reason,
-you'll want to keep the traffic on it low, so that people don't mute
-it and miss an important announcement.
-
-Additionally, Zulip's notification bot uses this stream for its
-messages.
-
-## Send an announcement
-
-1. To send an announcement, click the **New stream message**
- button located at the bottom of your screen.
- A box similar to the one shown in the below image will appear.
-
-    ![New stream message](/static/images/help/new-stream.png)
-
-3. In the **Stream** field, input `announce` to select the `#announce` stream.
-
-4. Enter the topic for your announcement in the **Topic** field.
-
-    !!! tip ""
-        Your topic name cannot be longer than 52 characters.
-
-5. Enter your announcement in **Compose your message here...**
-  (also known as the compose box).
-
-    !!! tip ""
-        You can type `@**all**` to mention everyone subscribed to the stream you
-        send the message to.
-
-6. Finally, you can now send your announcement by
-  clicking the **Send** button or by pressing the enter key
-  (if you have checked the option **Press Enter to send**).
-
-!!! tip ""
-    You can always cancel your message by clicking the x (<i
-    class="icon-vector-remove"></i>) icon located at the top right corner of
-    your compose box or pressing the `Esc` key.
-
-
-!!! warn ""
-    **Note:** By default all users are subscribed to the `#announce` stream,
-    but users can unsubscribe from and mute the stream. This means that
-    announcements, although organization-wide, will not reach users who
-    have muted or unsubscribed from the `#announce` stream.
