I searched the mailing list and did not find any reference to the following.
Is there a reason why Richard Dillon's YouTube Hack Emacs org-mode talks
are not included in the Org Tutorials? For instance
An overview of Org Mode -

Org Mode in Depth:Managing Structure -

There may be others. They're part of a multipart Emacs series.
I believe that they provide another introduction to Org Mode even if
slightly out of date.
