Google-calendar – change video chat provider for Google Calendar

There's an article on this here. I've not checked that it works, but it seems pretty straight forward. The essence is that instead of importing the calendar, you add the URL of your event feed as a public calendar - here's a summary of the steps:

1. In Facebook click on "Events"
2. Click on "Export Events" and copy the URL
3. In Google Calendar go to "Add" under "Other calendars" and choose "Add by URL"
4. Paste the URL you copied from Facebook and click "Add"

If you run into issues with private events not showing properly then check out eventbusyfix.info. This site acts as an inbetween to clear the private flag and enable Gmail to show them properly (Thanks to prestomation for this tip)

Hope that helps!

So, there's no way for you to change which of your calendars is the default. However, a fairly simple workaround is to import a new calendar that has all of the events from your default calendar. And then remove all the events from the default. So, that way, when you get invites, you can name the default calendar your Invites or Events or something.

To do this:

1. Go to your default calendar's settings
2. Click the ICAL option for the Private Address and save the .ics file to your computer
3. Create a new calendar
4. Click the Add dropdown and select Import Calendar
5. Select the .ics file you just saved, and import it to the new calendar you just created

Voila! Now you have a new calendar with the original events and you can delete all the things off your default and let it only have the invitation events.
