I was brainstorming some stuff with some friends about the new calendar when it occurred to us that the calendar might potentially be used to store data. I did some testing and was able to store a lot of different events on the same day. I think I made it up to 20 on one day. As of right now the calendar will store events through Oct 2009. You cannot add events for days past.
I guess some questions are : Could you store DkP data for example on the calendar? It seems pretty ideal. You can store a list of names, a description ie a point value, and a name for the event. Even the time could probably be used for something.
