Trainees register through a unique exercise URL, provided in the registration email. Players will have to register with their email address and will receive an email to set up their password. Once completing the registration process, they can log in with their credentials.

The facilitator will receive a notification in the exercise control feed every time a player registers. Whilst the players are waiting for the exercise to start, they will be provided with some messages to familiarise them with the technology they will be using.
