Jorge Segarra (@SQLChicken) has put together an idea to have on-line basic lessons on SQL Server called SQL University. The idea is to present two to three lessons each week in a somewhat academic manner, one that will hopefully encourage learning. It is targeted at the new or "accidental" SQL Server DBA. In this endeavor he has asked around for others in the community to pitch in and help. I've volunteered to take on Security Week (sounds like Shark Week, a nod to my friend and fellow SQL Server MVP, Frank Kalis, who loves sharks).
Jorge has already gotten the first week of lessons up. In addition, he should be making an annoucement soon as to some of the other faculty members as well as the athetic director so stay tuned here:
