Here are a variety of video/screencast resources for Drupal.
If you would like to add a video to the section, add a new child page under the most appropriate topic below, after reading at least the Policies section of the Contribute your own Drupal Videocast page.
If there is not already an appropriate topic, first create a child page for the topic, and then add your video description as a child page to that section.
If you want to create a page to describe your video repository, add it to the Video Repositories section, not here.
AGAIN: DO NOT ADD CHILD PAGES DIRECTLY HERE. Add them to a sub-topic and read the Contribute page lined above.
