To see a list of the members of your board, click on the 'Governing Board' or 'Trust Board' tab (this is usually the 4th tab on your board's page).
You can then see a list of everyone on your board, with their member type listed below their name. You can spot those who haven't yet set up their GovernorHub account by looking for the "has not yet registered on GovernorHub" line underneath their name.
The following labels will also show next to some people:
A green 'Admin' label for the people who have admin rights over the board
Blue labels to show which committee(s) the person sits on
Grey labels for all the roles the person has
