There are two reasons why you might want to create additional User Groups beyond our default user groups: You want to specify unique permission sets for users – Examples of this can be found below: Let’s say you want to give your Customer Service team the ability to create new users in Documoto, but not have access to everything else Admin related (ex. Library Admin, Storefront Admin, System Settings). In this case you might create a user group called “User Admin” and only give this user group permission to access to “Organization Admin”. When you create and assign that user group to your Customer Service team users, this would give those users the ability to create new organizations and users. Let’s say you want to give a subset of users the ability to “Add Comments” to Documoto on parts, pages, chapters, and media. You might also create a user group called “Viewers with Commenting Privileges” and give that user group the privilege to “Add Comments”. Another reason might be to restrict access to certain features – As an example, we have some customers that use “Attachments” for internal purposes only. In this case they have two user groups for viewers. One called “Internal Viewers” and another called “External Viewers”, where only internal viewers have the privilege to access attachments. Media Categories are assigned at the User Group level. If you loaded an entirely new category of content, (as an example “Marketing Materials”) and you only wanted to give specific users access to that category, you might create additional user groups, such as: Viewers user group: Media Category access includes Parts Manuals Operator’s Manuals Distributors user group: Media Category access includes Parts Manuals Operator’s Manuals Marketing Materials
