I get a lot of Facebook event invitations and while it's not too hard to go to the Facebook site and see my calendar there, I'd love to have the events show up on iCal on my iMac. Is that possible?
Now that I've moved from iCal to Google Calendar (see Import iCal to Google Calendar) I now need to figure out the second step: how do I mark this calendar shareable so that the rest of the people in my office can view it and add events, as needed?
