Logger installs with a default Administrator user, who has full permissions to create other users and assign them access permissions. When users require a specific set of permissions, you can create a custom User Group with those permissions. To do this, see Creating a New User Group.
To assign Logger permissions to a user:
From the Assign to Groups section, select one option from each group type. For new users, the default selection is "Unassigned." A user must be a member of at least one User Group to use Logger.
