Participant addresses can be modified from the participant manager. Only users with sufficient security privileges can modify participant addresses. The application also keeps a detailed record of all previous addresses that a participant has used. When modifying the primary address, it is not possible to remove the primary indicator. To change the primary indicator to a different address, the user must create another address and change the new address to primary. An existing secondary address can also be changed to a primary address. Setting an address status to primary automatically overrides the primary status of any previous address associated with that participant.
