Earlier this year, I was fortunate to visit Dublin, Ireland to speak at the Irish Microsoft Technical Conference (IMTC). Chuck Boyce from www.SQLServerDVD.com
was there recording and streaming sessions. He was unable to stream my session live, but he did get it recorded. Chuck has just posted my session on SQL Server Express 2005 (2008 wasn't out yet). Check out Chuck's website and perhaps learn something about SQL Server Express.
