thanks guys,
i've already contacted one of the websites and i'm stiill waiting for a response. but one last question... how about just linking to the videos? for example if i had a website on artifacts, can i just say... "for an amazing artifacts video, click here"? should i also use a reference for that link? or would a reference be unnessesary because they're going to go to that website anyway and find out who the source is? thanks.
