Here is where we bring awareness to Drupal modules running on less than 1% of reporting sites. Today we'll investigate Required by role, a module which allows a field to be required for some roles but not others.
NOTE: Tutorial begins at 2:27.
These posts are likely a great means of providing exposure to lesser known modules, but dedicating half of the total video length to unrelated drupal events and organizations is pretty poor form.
ColdSun, thanks for your feedback. I've updated the description to indicate when the tutorial begins.
