Searching around on the net shows this to be a real problem for others too. What bothers me most is that there's data for me that exists in google that has triggers to do things to me and other people that I have NO access to.
The solution? Shut off google calendar for crickers.com again. Just means my home calendars have to be hosted elsewhere.
But do you really own and control your data when its on google? It would seem not from the evidence.
