Can I prevent an Admin user from changing his privileges?

Sign in to your Revest Suite online account.
On the upper right corner, and next to your name, expand the arrow in the top right corner and select the Manage Admins option.
From the Manage Admins window, click the Edit icon for the admin you want to change his/her given privileges.
From the window that will open, set the Manage Admins privilege to either View or None → Save.
