If you have a Google account (https://www.youtube.com/), the YouTube widget shares a single video from YouTube to members. The video appears to members inside the working area, with the same controls that they would expect if they were accessing it directly from YouTube.
One use for this widget would be to include one of the numerous informational videos which are hosted on YouTube in a Space.
Click the Launch YouTube Chooser button to launch the YouTube chooser to choose a video to share. The chosen video appears beneath the work area.
You can share only one video at a time with this widget. If you edit the widget and change the video, the new video replaces the old one.
