Remove email integration from calendar in mountain lion? I've just got a new laptop with Mountain Lion. The calendar has the old color coded options of 'Work', 'Home' etc, however it also has my email address as an option. If I select 'Work' and create a new event it automatically changes to the email account, meaning that I get email alerts for events,  which I dont want. 

How can I change this behaviour? 

UPDATE - Actually I want to completely remove Google Calendar from my mac calendar so i dont get email alerts either. Thanks
To Remove the Calendar completely. 

Go to the Mail, Contacts &amp; Calendars Preference in System Preferences select the google mail account and uncheck the Calendars &amp; Reminders
