To add a new administrator to your LMS platform, you only need to access the Daily Management> Administration section in your backoffice and click on the "Create new backoffice user" button. In this new section you will be able to enter the user's data and select the administrator role.
Depending on the plan you have contracted, you can have a certain number of administrators. In the START plan there is only one administrator user. The ADVANCE plan can have up to 3 administrator users. And in the PRO plan there is no limitation of administrator users.
