First of all, on my behalf, and on the behalf of all of the staff and members here, I'd like to say welcome. This forum is obviously for youtube vids... Let's have a quick lil' tutorial for how to do this.
OK, so I rather like the video for "Holy Smoke" by Iron Maiden. And I'd like to post it. How do I do this?
It's quite simple: all you need to do is click the youtube button above your text box!
Here's what you should get when this guy is pressed:
[youtube]
And when it's pressed again:
[/youtube]
The first one opens up the tag. The second one closes it. These are both crucial to this process.
This here is the link for it:

So, here's where all this comes into play: You hit the youtube button, copy the link in, and hit it again to close it. And then you hit your girl.
Thus:

Resulting in:
