Abstract: A computer system for scheduling events between end users of the system. Each end user is granted a unique password protected personal calendar. This calendar is generated from information stored in a database at a central server, and delivered to each end user as standard HTML sent through the Internet. This custom personal calendar is then viewed by the end user in a standard Web Browser. This obviates the need for special software programs to be purchased by end users, and also allows end users of any CPU type to read their calendars. When an end user uses the system to send an Invitation or Announcement to others on the system, the sending end user has the option of sending Email in addition to posting that information in the calendars' of others. When an end user sends an Invitation or Announcement to a person who is not an Appointnet user, then the Appointnet system automatically creates a unique calendar for the recipient, and sends and Email to that person.
