I have added the ability for you to add youtube videos to your post. When you start a new post there is now a "BBCODE" for YouTube. To add a video to your post just:
1. Start a post like you normally do.
2. click the youtube button and you will see [ youtube ][ /youtube ] (I added spaces to the code so it would show up in this example)
3. Then go to YouTube and copy the full URL from the URL window on your browser
4. The paste it between the youtube tags. The line will look like this.. [ youtube ]http://www.youtube.com/watch?v=3aHSlhUjmO8[ /youtube ]
The result is this
