I want to share a calendar with 3 or 4 other people. I am looking for the simplest approach; one user is highly non-technical. I tried using Google Calendar but she would keep adding events to her personal calendar thinking it was the shared one. Under the "My Calendars" heading, I selected to only display the shared calendar but it appears Google Calendar by default re-shows the personal calendar after a new event is created. Can this be changed? Is there a simpler alternative to Google Calendar?
