Remove Admin User

How can I remove my trainer from my account? He listed as an Admin.

Assuming you are an admin as well, if you go to settings (top right), click on users, click on the name of the user and the scroll down to the bottom you will see the word ‘Deactivate’ - click that and they no longer have access to your system.

There is no delete option, that is due to audit trails (or so I’ve been told previously)
