You can use the banner to tell players when to return from a lunch break, inform them that a particular machine has broken down or anything else that strikes your fancy. ### Adding an announcement banner * Go to the tournament **Overview** page * Click to open the **More…** menu * Click the **Announcement banner** menu item You can enter a short announcement, pick a color and optionally an expiration time. For technical reasons it may take up to five minutes before all players see the announcement banner so keep that in mind. You can remove the banner again by clicking on **Announcement banner** again and then clicking the **Clear banner** button. It may also take up to five minutes before the banner disappears for all players. --- # Agent Instructions This documentation is published with GitBook.
