There is no practical way to share Calendars with Lightning at this time. In previous versions you used to be able to use remote calendars with url's like this: ftp://user:password@www.someserver.com/calendar.icsIt was so easy to subscribe to and use calendars, but this no longer works.I'm sure there is some way to use a calendar on a webdav, but it is absolute hell to setup webdav, so no one will ever do that.Your best bet is to not use Lightning until sharing of calendars works. Check back in about 2 or 3 years.
