...and hundreds of video entries, you've proven that you want to use
your video-making skills to help each other use YouTube. We liked your
videos so much that we've decided to make them a standing feature in
the Help Center.

Now you can submit videos to accompany all of our Help Center entries.
And there is no deadline, so you can keep sending us videos over time.
To submit your video, just go into our Help Center and pick from the
hundreds of entries.

On the right hand side, you'll see a gadget where you can submit
videos you've previously uploaded or upload a new one.

Pick the entry you think is funny, incomplete, too short, whatever!
You can share tips you've discovered while using YouTube, tell your
story through a funny sketch, a song, an animation -- we're sure you
can come up with lots more ideas than us! We'll take a look at what
you put together and will embed the ones that best accompany each
article right there on the Help Center, where millions of YouTube
users will see it.

Thank you for helping us help other users -- we can't wait to see your
next idea.

Keep those cameras rolling,
- The YouTube Help Team
