The notification center allows us to turn off alerts for the Calendar app, but that is for ALL of our calendars. What we really need is the ability to SELECTIVELY TURN OFF ALERTS for SPECIFIC CALENDARS ONLY. So, for example, we WANT to get alerts for our "personal" calendar but not for our "work" calendar. Think about a set of calendars which are shared amongst a small office, where every employee has their own calendar for their events... I need to SEE other people's calendar events, but I don't need to be ALERTED to other people's calendar events.
