Not that the other issues aren't worthy, but the management of DNN's SQL database greatly extends the administrator's capabilities and can lead to automation of tasks as well as simplified tasks.  I've worked with SQL for just about forever, and still learned from these tutorials.  Beginners to SQL should find this series easy to follow, as with all of Lee's videos, since the explanations and walktrhoughs make sense from the very beginning.

Keep up the good work.  Now all I need from you is a lifetime subscription.
