An Administrator of a LityxIQ instance has the ability to add users and user groups, assign users to groups, modify and manage permissions, and other functions. The available options are located in the Admin menu found in the left panel of LityxIQ. If you do not see this menu, it likely means that you do not have access to any of these options. The options you do see may be different than shown below, again, depending on the permissions you have been granted. Please also have a quick look at Admin Recommendations for some good practices for managing the LityxIQ instance.
