An Icalendar feed of the next year's worth of scheduled DCS Seminars can be added to your Mozilla Calender application (i.e. Mozilla Sunbird or Mozilla Thunderbird with the Lightning add-on).

Go to the File menu and select New Calendar (or New and then Calendar). You will be asked whether the new calendar is on your computer or on the network. Select On the Network and hit Next. You will be prompted for a format and a location. For Format, choose iCalendar (ICS). For location, paste in the following link: 

http://dcsweb.cs.toronto.edu/cgi-bin/ics.cgi/http://sites.utoronto.ca/reg/list_notices_p.pl?dept=csci&time_frame=year
Hit Next. Give your calendar a name and optional colour, and indicate whether or not you want to see alarms (when a seminar on the calendar is about to start).
