Withdraw or correct a note
Send the earlier reference and state what should change. For a removal request, use the same email where possible so the relevant record can be located.
Improve a rule explanation
Quote the short rule heading and describe the uncertain situation in your own words. Reporting a problem does not require identifying the other players. Nothing on this page limits a right that Australian law makes mandatory.
