I wanna see that!
Go to youtube (or wherever) and copy the link (highlight it in the web address box and control-C on a PC, or command-C on a Mac), then come here and when you're posting, press the button that looks like an old school film (2nd from the right) and paste (control-V on a PC or command-V on a Mac) the link in the box that shows up:up:
Alternatively you can just paste it to your posting and type:
{video}in the front of the link and {/video} at the end... but put brackets "[" and "]" instead of braces "{", "}"
BTW same goes for pics (button 3rd from the right) and "choose" the pic from your computer or a website, OR
use {img} put photo link here {/img} but with brackets instead.
