How do I chat?
In the chat area you can enter what you want to say in the chat field at the bottom of the chat area, then press enter.
How do I send a whisper/private message?
You can send private messages to another user by typing /t <username> <message>
Where <username> is, replace this with the screen name of the user you are sending the private message to and <message> is your message.
Example: /t MeganBoom_Admin Hello Megan.
