To use Rabb.it, a host had to generate a room and send requests to others to join it. As a substitute, the host can make the room open to the public so that it is noticeable on the homepage of the site. In this way, anybody can participate in this room and share content with the help of a virtual machine known as “Rabbitcast”. Alternatively, they can also use the “Share on Rabbit” Google Chrome extension. A sign-up option with Facebook was also available for the users.
