In late May, changes were made to a user's Eventor profile making a contact email mandatory, and separating the previously single emergency contact field into two fields.

Orienteering Australia recommends that all users log in to their Eventor account and review their profile settings, especially for emergency contact details, and ensure that all details are correct.  This document might assist you making this change.

At the same time, if members have not yet done so, they might like to check all their other details and complete their diversity data profile.
