I installed gpe-calendar on my N810 along with COntacts and todo.

After reading this thread, just now I imported Google Calendar ical using the ical address for my GCal.
The first time it failed saying the URL does not exist. So I made my calendar public and did a refresh on my gpe-calendar app on and I can get all my Google calendar events in gpe.
This is great. I did not even know this could be done.
Great way to have one view of my persoanl IT based events and the collaborative GCal calendar.Maybe having todo and contact (I also installed GPE-summary) might help resolve the issue.

But can I import my GCal wihout having to make it public and open to everyone ?
