Videos that you feel are irrelevant to the topic of your wiki, or contain content that you wouldn't want your members to see, should be deleted from the gallery so that users may not view it.
Note: In order to remove a video from the gallery, one must be a moderator, administrator, or site creator on the site.
Steps
1. Go to the video gallery
2. Click on the video you wish to remove
3. Click on "More tools" at the top of the page
4. Select "Delete video" from the drop down menu and confirm that you want to delete the video.
What if this video is on pages, too?
A video may only be deleted from the Video Gallery. To remove a video on a page it has been added to on the site, navigate to the page it resides on and use EasyEdit to delete the video.
