Our calendar now hangs on the right side-bar and in primary links. This beauty is made using Date, Calendar, and a bunch of other Date/Time modules1. The Calendar module provides a nice group of views (page, block, upcoming, etc..) which we used to display information from our CCK-based Event content type.
iCal feeds are made available by activating the iCal module. You can now import our calendar by clicking on the cute "add to calendar" link on the bottom-right corner of our calendar, or subscribe by adding the URL http://icarda2.benale.net/calendar/ical/ to your favourite calendar client.
