Google-apps – way to get Google Apps domain shared contacts to automatically show up in Google’s contact manager

This used to be available, but has been discontinued:

Note: The previous Start Page service was a syndicated version of iGoogle; it allows you to set up a dynamic homepage (one start page layout per domain) for your users that brings together your content, Google services, and the best of the web. Starting on 3 December 2008, the Start Page is no longer included for new organizations that sign up for Google Apps.

However, you can now make your own via Google Sites:

This page is your users' homepage, on which they can access their Google services and other content -- such as interactive gadgets and RSS feeds -- when they log in to their Google Apps accounts.their Google Apps accounts.

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"
