For future reference, when people ask how to embed youtube videos, please forward them to this stickied post!
To embed a youtube video anywhere on TDC where html code is accepted, use the following tag (If you can't remember it, it's available as a button in the toolbox):
< YouTube YouTubeID >
Where "YouTubeID" is the string in the URL after "watch?v=" So, for example, to embed the most dramatic chipmunk on the face of the planet on your project page, find the URL: http://www.youtube.com/watch?v=a1Y73sPHKxw
And take the string at the end, which becomes:
< YouTube a1Y73sPHKxw >
which without the first and last spaces becomes:
UPDATE: If you're where the toolbar is available, Clubsoft says this: You can also paste the URL of the YouTube video into the edit box, select the url, and click the YouTube button, which will extract the ID for you.
I hope that was sarcasm. I honestly don't think it could be made any easier. You replace YouTubeID with the video ID at the end of the link that takes you to the Youtube page. IE, the only part of the link that varies from video to video...
