When you are invited to a room, you will receive an invite email with instructions on how to join the room. If Chrome is your default browser, simply click the Enter Room button. If Chrome is not your default browser, copy the URL and paste it into Chrome.
When you visit the URL, you will be greeted by a welcome screen and asked to create an account. Enter the Display Name and Password that you would like to use, the click Continue.
You will then be taken to the "Pre Room", where you can adjust your settings and ensure your microphone and webcam are working, prior to going live and joining the room. When you're ready, click the "GO LIVE!" button.
