I've made a Google calendar for the Liberal Democrats spring conference.
You can subscribe to it at this address: http://www.google.com/calendar/ical/eiloart.com_ov92vs7r372538okh8ibq1uefs%40group.calendar.google.com/public/basic.ics
There's little chance that I'll update anything on the diary now (unless you tweet @ianeiloart with errata), so you're probably just as well to add the events by clicking here: http://s.coop/ldconf2012
