I've posted on youtube for the first time in my life
 

You know you can delete or hide your videos. So that one that didn't come out right you can get rid of it and not have to ask people to 'please ignore this post'

Go into "My Videos & Playlists" ( to do so, check at the top right, your login name should appear. Click it and six choices will come up. One will be "My Videos". That will take you to the relevant screen) and a list should come up with your videos. If you check the check mark on a video, you can then push the delete button just above your videos and delete that one that you checked. Or, you can edit a particular video and change its privacy setting to private.
