Since a lot of us like to post videos from youtube this might help.

First you click the YouTube Button underneath the Subject Bar

And the YouTube Code should appear in this space of the screen.

Select the Video from Youtube and Copy the Embed Code, on the right hand side under the URL.

And paste it into this screen like this:

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/HdM8gmLSrrw&hl=en&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/HdM8gmLSrrw&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

Now, all you need to make the video viewable on the forum is this URL from this code which is in bold above.

And Copy that URL and post it into the Youtube Code Like this :




And Click Preview to make sure It worked!
