https://www.youtube.com/v/eUnVlVBuhW0For those of you who don't know how to embed the video (Like I didn't!) Just do it like this:
1. Hit the reply button (full reply not quick reply)
2. Right above the row of smileys the first button is a red circle with f in it (flash). Click that.
3. It will write out a template for you. by default it makes the height and width 200 and 200. On the youtube page you can find the proper size and change these by going to the share > embed code. (don't need to use the code, just look at the height and width numbers in the beginning.)
4. In between the ][ insert your url.
5. Your youtube url will be something like this:
https://www.youtube.com/watch?v=UIo9Aq0yazQ change the part in bold to simply v/
6. That should do it.
