There are two livemeeting webcasts scheduled which you might be interested. The first on the new datetime datatype is scheduled for 9pm GMT tomorrow and the second, on Ordpath, at 9pm on the 28th. To participate I've posted the links below but if these don't work, or you need more details, then go to the connect site and navigate to the SQL Server 2008 content page. Listed on that page you will see a link to all the upcomming SQL webcasts.
