Rated 5 out of 5 stars

absolutely excited!!!! together with the Add-on Provider CalDAV & CardDAV thunderbird finally gets normal functionality in synchronising self hosted calendars and addressbooks. Before these add-ons you had to import each calender one by one, now you can subscribe to all of them with one single click. Perfekt. That's how it should be. Great support by John, helping to fix some xml-problems with my overcrowed addressbook. Big Thanx!!!!
