The boxing website is the url..

A url will be something like.. www.youtube.com/mnbsfdu=blablabla..

Litterally to the right of your video there is two little boxes and one says url next to it..

Right click it with the mouse and go copy..

Then right click the post your making and go for paste and it comes out..

And to upload before doing all of that you make a youtube account, once that is done go to my account and on the left hand side it says upload a video..it then gives you a few easy steps

Peace
