I used to use the Planzo online calendar, but this Google one just blows that outta the water. In fact, it blows Outlook out of the water. As long as you don't mind the Google Gods looking through the bits and bytes of your electronic private life so they can ad-sense you, this is one really cool calendar! Tripper showed it to me today and hell, you can label some items and toggle them on and off (all color coded). You can allow other people access to your event info and even give them permission to change them, etc.
