seeing as there are constantly reposts of videos and such, and the most common response being "I searchbared but found nothing", I think it would be a great idea to be able to search thread contents and not just the title. So say I'm watching a video and go ahead to post it, search but don't find anything since the previous poster had it under a thread called "cool trick" or something, then I could say search to see if that link has been posted in a thread before, and what thread it's in. that way you could also search for something that someone said, or a link to a news article or whatever the hell as been written in a thread.
just another thought
