I am running OS 10.8 server on a mac mini. I have the calenddar service enabled and created an extra user for calendars.
I have no problem subscribing to those calendars by creating an OSX server account on other macs using the "Mail, Contacts & Calendars" setting in system preferences.
Is it possible to subscribe to such a calendar online, using google calendar? Google Calendar has an option to "add via URL" (right click on further calendars at the bottom left) -- how can I figure out what the URL of my calendar is?
