New, Wider Layout For Your Channel
We wanted to give everyone a heads up that we'll shortly be expanding all standard channels over to the new 960 pixel width. This is the same change we made with the video watch page a few weeks ago, and will make channels wider and consistent with the rest of the site.
Have channel backgrounds you want to get ready for the change? You can get a sneak peek of what your channel will look like by visiting the following URL today:
http://www.youtube.com/user/YourUsername?wide=1
(e.g. if your username is "jane12345," then replace "YourUsername" in the URL with "jane12345" to see how your own channel will appear).
Holler at us with your feedback,
The YouTube Team
