I've been hunting on the YouTube.com web site for directions on submitting videos vie email. I couldn't find the instructions. If you know where this is documented, please let me know.
It would be moderately easy to add an item under the <Control>-click menu (right-click) that, when you clicked on a video, created a correctly formatted email message in Apple's Mail program, then sent it. But I need to see the directions from YouTube.com to know ow to formt the email so YouTube would take it.
I did find the directions on sending a video from a mobile phone, but there weren't enough details on that page for me to figure out how to implement it generally.
