These two:http://www.youtube.com/watch?v=1h8ZeYyRkIU and
http://www.youtube.com/watch?v=4l1n69jTArI They're a good contrast.
(it was in the name of space and i don't know how post vids)
It's quite easy. Type the following:
[ youtube=____________]
Fill in the blank with the video's identifying URL code ------the part in bold------>
http://www.youtube.com/watch?v=1h8ZeYyRkIU
So it looks like this -------> [ youtube=1h8ZeYyRkIU]
Now just remove the *space* from before the word
youtube, and you're good to go!
