In adition to the Lotus Notes 8 online tutorial there are two more tutorials available. One is for users migrating from Microsoft Outlook 2003 to Lotus Notes 8 and the other one is a tutorial regarding the productivity tools included within Lotus Notes 8.
BTW: The “official” starter page for these tutorial links is the “Lotus Notes and Domino 8 technical content” page on Developer Works.
