For years I have been frustrated by iCal and the fact that, unlike Outlook, you can't have private meetings, which are kept confidential when posted through DAV. Guess what? A colleague of mine, Colin Beagrie, accidentally found that if you put the event name in angle brackets, as in <Job Interview>, the meeting is not made public. This does not seem to be documented anywhere, but it worked for me, as well as Colin.

I wonder why we are both so keen on private meetings all of a sudden.
