iCal Exchange is now online. It was created to give
iCal users an easy way to publish their iCal calendars online without a .Mac account.
You can publish your iCal calendar to the iCal Exchange via the built-in “Publish to a web server” mechanism. When you share your calendars, visitors will be able to download the .ics file, and even view your calendar through a Web browser. There is also password-protection for individual calendars and an HTML view.
To use the iCal Exchange, you’ll have to create an account. iCal is Apple’s free personal calendar “i-app.” It requires Mac OS X 10.2 (“Jaguar”) and is available now for download.
