You can then type in your message and either press the Enter/Return key on your keyboard to send, or click the send button to the right to send your chat message, which may be up to 280 characters long. Your messages will appear on the right side of the chat window whereas others’ messages will appear alongside their names on the left side.

When the chat is open you can adjust how it’s displayed by clicking the ••• menu in the upper right corner. Minimize will show only a chat bubble icon next to the player, whereas Pop out will open the chat in a separate browser window.

If you choose Minimize, you can re-open the chat window by clicking the chat bubble icon. 

Note that the event chat is moderated by the event’s producer, who has the ability to delete or block comments from anyone.
