It's easy to embed utube stuff now... Check it, I'm going to do an instructional vid on this today as well
YouTube url's look like this:
http://www.youtube.com/watch?v=xwcDChzaJ2E
when posting, go advanced, and you will see a youtube button in the editor. Click it, and place everything after "v=" in youtube quotes. It's a piece of cake, check it out.
