I have 2 swap accounts set up. One is my job email and calendar, the extra is Gmail email/calendar. My Gmail calendar really has quite a few calendars in it. The majority of which I stay unseen. However, the calendar division in the notification all the time illustrates events from every calendar. There doesn't appear to be every manner to select which calendar's dealings illustrate up there. I would guess the Notification Center to simply illustrate future events from the checked calendars in the calendar application. I would a big shot be keen to take this as a bug?
