Hey Bill, it's no problem at all. I don't see what you've added, though. Do you have your own personal google calendar? If you do, and you added them to that, it won't show up on the public one. Look for this in the bottom left:

and make sure when you add an event you add it to the "Track Days 2008" calendar (you can set your own colour-coding so as not to confuse it with your personal calendar). Hope that helps.
