The People section is dedicated to configuring and managing your company's users.
It consists of two parts:
1. Directory
In the Directory you will find the users of your company who have or will have access to Nibol. Here you can manually add new members (if you don't have integrated active directory), invite them, modify and delete those that already exist.
See here for an in-depth look at how to manually manage your Directory.
2. Groups
In this section, you can divide members into different groups to set specific rules and constraints for using Nibol.
See here for more information on the Groups.
