To update a member's contact details on GovernorHub, head to the Members tab and click on the arrow to the right-hand side of their name in the members list. This will reveal a drop-down menu. One of the options is View Name's full profile. Click this button.

This takes you to a member's profile page where you can update their details and contact information. You can also update their declarations of interest and training records from the other tabs at the top.

Note: if a governor is a member of multiple boards, this will update their details across all their schools.
