Choose a title you can use to customize how you appear in chat and the TAB player list.
Run /titles list to see the title names you can choose and how each one will appear.
Run /titles set <title-name> with a name shown by /titles list. Use the name before the colon; the formatted title text in quotes is how it appears in chat and the TAB list.
You can select one title by default; if your account allows multiple, add each name after the command, separated by spaces.
Run /titles set with no title name to reset your selection.
Your list shows titles available to you. Some titles form progressions such as playtime ranks or voting; it shows only your highest available title from each progression, while other titles appear individually.
