What is a preference group?
A preference group is a collection of default preferences and application settings. Administrators assign individual users to one preference group per product, and the user inherits the group's settings. Users who share the same preference group usually have similar jobs.
For example, if you have a Personal Injury group, you may wish to set the Personal Injury Damages form as the default home page for this preference group. All members of the Personal Injury group will then automatically receive this setting. Users can override any of the default preferences unless you lock the options.
Or, if you want all research that the Corporate Tax group conducts to be encrypted for maximum security, you can change the group settings for their preference group to require an SSL connection for their entire research session. Users cannot override any of the application settings that you assign to a preference group.
