I often receive invites to events via Gmail, and wish to add them to one of my calendars in Google. When I click 'add to calendar' (or equivalent), I see the usual drop-down to allow me to choose between calendars. When I click on this drop-down, however, the only option is my primary calendar (the one with the same name as my Google account).
So...is there a way to add events to one of my other calendars, or do I just have to make a copy of the event if I want it outside my Google account primary calendar?
