You may embed YouTube videos into posts here. Click the far right icon on the second menu line of the edit window. It looks like three photos in a stack (blue, purple, and green). Then copy and paste the entire address from YouTube and click "Insert Media". The shorthand is to type "[ media ] http://www.youtube.com/watch... [ /media ]" without the spaces inside the brackets.
Don't forget to click the "other styles" menu (at the top left) and then "tab" (at the bottom of the list) to ensure that the proper spacing of your tab will be preserved in the post. The shorthand is to type "[ tab ]------0-----2-----3[ /tab ]" without the spaces in the brackets.
