Multiple Calendars

I have members who each need to create separate calendars. I have three questions:

1. Can each member have a separate calendars in one install? Each member should be able to see only their calendar and no one else’s calendar. Is this possible?
2. I want to use Gravity Forms to allow members to add their information via the WP front end. Do members have the ability to view, change, update their calendar info?
3. Can reminders be send with this plugin (email and sms)?
