iCal is great for managing your life, but it’s also designed to display other people’s calendars. In fact, the real power of iCal comes from its ability to share calendars so you can see what your family, your coworkers, or your
As you've seen, when you
You can share your calendars in two ways: you can export them or you can publish them to .Mac (the latter option is only available if you have a .Mac account; see Chapter 11 for more on .Mac). If you publish a calendar on .Mac, others can view them in two ways: they can see the calendar on a web page, or they can subscribe to the calendar and view it in their copy of iCal.
If you export calendars, you save them as files that you can send to others. To do this, select a calendar in the Calendars list, and then select File Export. This saves the calendar as a file with an .ics extension. Send this file to someone else, either over a network or by e-mail, and all they have to do is double-click the file to add the calendar to their copy of iCal.
This is a good way to share calendars for fixed events, such as a school schedule, a sports schedule or other calendars that won’t change. But even if the events do change, you can make changes on your calendar and re-export it, or the other person can add or edit events, export the calendar, and send it back to you.

Publish Changes Automatically If you check this, iCal updates the published calendar whenever you make any changes, as long as you have an active Internet connection.
Publish Subjects and Notes This publishes subjects, or the names of your events, along with any notes you have added in the Info Drawer. If you uncheck this, your published calendar will show others when you are busy, but not what you are doing.
Publish Alarms This also publishes alarms. These alarms are only accessible if other users subscribe to them with iCal (see the upcoming “Subscribe to Calendars” section).
Publish To Do Items This also publishes a list of To Do items (see the “Manage To Do Lists with iCal” section).
Publish Calendar You can choose from publishing on .Mac or on a WebDAV server. The latter is usually only available on corporate networks.
After you publish a calendar, you’ll see a Calendar Published dialog confirming that the publication was successful. (If you don’t have an active Internet connection, or if there are other network problems, you’ll see an error message.)
This dialog shows the URLs that can be used to view or subscribe to the calendar; you can select these URLs and save them. The dialog also has three
