I was working with a client setting up a YouTube channel and had an interesting learning experience. The client wanted to change the name of one of his newly created playlists and was unable to do so.
He tried clicking on the list on the left, then right clicked on the name in that list; clicked on the name of playlist ; then searched the buttons above the videos -- with the mouse moving back and forth [red box], left and right over the buttons; then clicked the drop-down arrow next to the ADD TO ; went to change screen icons on the right ; went back up to his Channel Name and chose the dropdown from there.  Came back this screen and gave up.
A co-worker spent at least 15 minutes looking around the Google YouTube help pages without able to find it. Both the client and the co-worker are experienced "expert" computer users. Both missed where they were supposed to go. Both assumed -- because of YouTubes low functionality -- that they would have to delete their playlist and create a new one.
Both couldn't believe it when I showed them the link.
How illuminating it is to watch users in action.
So, how does one edit the name of the playlist?
If you're on your "My Channel" screen (not on this screen) you have to:
1. Select the drop down by your channel name
2. Select Favorites
3. On the left column select "Playlists"
You are then at "this" screen.
4. Select the drop down by "Edit Playlist Info"
5. Edit the title (should be clear at this point)
