A Key Contact is no longer with us. How can I remove their access to the Dashboard or remove them from our MTN account?

On your Approved Members page under Settings on your Dashboard, you can change a member status from a Key Contact to a Regular Member. If they are no longer with the organization, you can change their member status to Deny instead of Approved. If you are only Key Contact and original creator of the organization, event or team, and you want to remove your own association you will need to assign another Key Contact to change your status to Regular Member.
