Manage other users' account management levels by going to Settings > User Management > User Levels > New User Level.
Here you can name your user level and indicate whether this level has the power to manage other users. From there you can set all of the various permissions throughout your account for this level and save when you're finished.
Administrators can set permissions across the board for the account. From Data Analysis to Tool permissions and everything in between. Choose if you'd like a specific user to be able to "Edit & View" certain items, only "View," or have neither ability by checking the corresponding box.
To help you get a better visual of your user permission levels click the "View Org Chart" tab.
