Facebook and iCal: BFF
Go to your Facebook Events page. Click “Export Events” at the top of the page. Copy that URL and subscribe to it in iCal.
Yay for open standards!
[Edit:
Oh. So if you want to move an event to your calendar, you have to cut/paste. At which point iCal will insist on sending email to the “invitees” which is just the planner of the event. And then when you remove the event from the calendar it insists on emailing the planner that the event is cancelled.
Er. -1 for emails unexpectedly sent in your name.
