Andrew just take the youtube video's code after the = sign in the URL and enter it between the brackets when you type \ youtube{}. Minus the space between the slash and youtube.
Also, if you scroll all the way down while browsing this or any thread, there is an option to click where it says "formatting tips" which shows you how to do things to the font when you post, or embed videos and URLs, and use symbols and icons etc.
Yeah, Brad could probably use some tips based on that other thread. But give him time, it's tough when you're new at computers and you aren't very tech savvy. He'll be okay.
