I've added support for embedded youtube videos. To add them, first click on the youtube icon in the posting bar (the area where you can change the font / add images, etc).
It will popup a message asking you for the option for your youtube tag (confusing I know).
Here you should enter the TITLE for your video. It can be anything you want.
Next, you will see this
PHP Code:
[yt="this is a test"][/yt]
between the brackets, you should enter the name of the video. For example, if you are trying to link to this video:
Code:
http://www.youtube.com/watch?v=v_ZC_k8TK30
the title would be v_ZC_k8TK30
So, your finished code would be:
PHP Code:
[yt="this is a test"]v_ZC_k8TK30[/yt]
