Rated 4 out of 5 stars

Johan Hellstan: I'm not sure why I'm posting this to help someone who is so intemperate about a free add-on to a free piece of software being used to access a free web service.... but here goes.

Google changed the text. You now want 'calendar settings'. To get to the calendar settings click the little down arrow next to the calendar you want.

You'll see some icons, right click to copy the XML link.

This review is for a previous version of the add-on (0.5).
