Folder Set up
Go to Manage → Knowledge base → Folders to set up your folders.
Use folders to manage who can create, read, edit and delete which articles.
You can create subfolders by clicking on a folder and pulling it under another folder. For the automatic unwrap submenu check the box in the main folder.
Click the admin symbol to select which user gets rights to view the folders.
Go to Manage → Users → Rights → Knowledge base folders to set up user permissions.
Users with edit rights will receive a notification when someone comments on an article.
