When you learn of a close relationship between two or more of the people you have on record, go retrieve the name & address of one of them, then come back here. Their name should now be in the name field at the top. Press the Everybody button. A scrolling list of everybody else on record is displayed in the window. In this list, find and click the name(s) of the other individual(s) whom you have discovered that they know. Now press the Friends Only button. The window now shows the names and reference numbers of their 'friends'. These newly selected names appear in addition to any which were already on their list of friends. Now double-click the name of one of the new friends. The applet now changes to the view below.
The name of the friend now appears in a second name field and the main window clears. In the window you can now type-in a description of their relationship. Very useful knowledge for business. You can add to or amend this description any time you learn something new about their relationship. Note that the Back button takes you back to the first applet above showing the list of the person's 'friends'. To delete a 'friend' from a person's list, click the name once to mark it, then press the delete key on you computer's keyboard.
The above boxes are simply images. When implemented as applets, the operation of each button is displayed on the browser's status bar when the mouse pointer is over the button concerned.
