The Workbench suite introduces huge improvements to the way content is managed in Drupal. Workbench provides a single user interface for users to work with content.Workbench adds usability improvements so that there's no need to "learn Drupal". It allows you to set editor permissions based on your organization's structure, not your website's.
You can even create editorial workflows that allow users to create content, but not publish it, while other users may review content, and decide whether it needs an additional revision, or that it is ready to be published, and do so.
I got back into Drupal about a year before Drupal 7 was released, so I built a couple of sites in Drupal 6. Then in January I completely switched over to D7 when it was released. Because I decided to make the switch right away, I was running into a lot of bugs/issues that hadn't been resolved yet. So, I started to make videos helping other people with the problems I found.
With the videos I made, I realized that I had shown some solutions, but people still had a lot of questions about edge cases. That was when I saw the light, and had the idea to put together series of short videos covering different topics. This format allowed me go in-depth with each module. I'm glad to be sharing these videos on OSTraining!
