On the 1st of February, you will receive an invitation from DutyMan.
You will be required to log in via the link in the email to choose a minimum of 2 duties that suit you. It is on a first-come, first-served basis, therefore it is in your best interest to access DutyMan sooner rather than later.
It also hosts a function of being able to swap duties in the future if something comes up. In accordance with the HISC rules if you do not volunteer you will be allocated duties.
