Displaying Your Rank Icon
You can choose to display what rank you are in the Order of the Moon by typing /order into chat. This will bring up a dialog box giving you the option to display an icon for either Order of the Moon or Order of the Crow (but not both). You can also choose to hide such icons altogether.
The Order Of The Moon was added in June 2015, but the ability to display its icon was not released until February 2016.
