Jacob - thanks for letting us know you deleted it. I was the person who added it, on behalf of the organizer. I would have eventually noticed it was missing and re-added it.
With a totally open calendar, that will happen, surprised it does not happen more often. Usually we just get spammers who change past events to point to their Viagara selling sites.
If you accidentally deleted it thru code, then let us know what sort of app you are playing with. The people who have developed other apps that access the calendar are all here. I bet they would be interested to hear what you are working on. But you might have just fat fingered it, like I do often!
