The community should be able to help update outdated videos

Looking at all of the old and outdated champion previews and ability videos, why couldn't the community help out with that? Riot could even make it a contest, like for a certain champion, people send in videos and Riot gets to choose which ones are kept for the new ones, maybe having a reward for the person whose video was picked. And ability videos wouldn't be hard to do at all, those could just be sent in whenever.

Or something. I think this would be a great idea.
