On our University sharepoint site we have a department calendar where dates for the entire department are put. I would like to create a sub calendar that for just events that appears in the main calendar. It would also be useful if the events calendar could be turned on and off by individuals so they can choose to view it or not. I notice next to the department calendar there is a link labelled 'calendars in view' which would lead me to believe sub calendars are possible. Any help I could get with creating these sub calendars would be greatly appreciated.
