turn off email notifications
All of the sudden when I create or change an event in iCal everyone I share the calendar with gets an email telling them of the change. This wasn't happening when I set it up . These are calendars I really need to share but it's unnessesary for an email to clutter the inbox of multiple people every time something is added or changed. Anyone know of a way to turn this off?
OS X 10.7.3
iCal 5.02
