You can change a number of Preferences to control various aspects of the way the MemberTies behaves. Many of the Preferences, such as the database profiles, are required, and MemberTies will not run correctly if they are not provided.
Preferences are divided into various categories, which represent the area of the application most affected by the setting. Things that do not fit a specific area of the application are found in Miscellaneous preferences. Within each category there are normally one or two types of preferences:
User Preferences - identified by the "person" icon, are specific to a given user name. If you log in as "bob" and set a user preference to "A", someone else can login as "john" and set the same preference to "B". The system will use the appropriate setting based on whether Bob or John is logged in at the time.
System Preferences - identified by the "computer" icon, are global across the application, and apply to every user. Following the above example, if user "bob" logs in and changes a system preference to "A", and later user "john" logs in and changes the same setting to "B", the setting "B" will be used the next time Bob logs in as well, because John has changed the setting for everyone.
Note: In a multi-user installation, a change to a System preference made by one user may not be noticed by the other users until they log in again. This is because preference settings are stored in memory at the time of Login, and only refreshed from the database periodically.
If you're the only user on the system, then there isn't really any difference between User and System preferences. You just need to be aware that if you create a new user and start logging in under that ID, it will have its own set of preferences.
Note that if your security group settings prevent you from editing system preferences, no system preferences will appear for you. This could leave some categories completely empty.
Preference settings vary from simple On/Off settings, to complete data-entry screens to control more complicated features. The example above illustrates the (user) preference to control alternating row stripe colors on lists.
