Delete, please.
 

I wanted to pull my wow movies from youtube to wcm, so I started with the old ones. Actually I uploadefd the first one, and wrote it in the description that its one of my very first videos back from tbc when I was totally a newbie. People don't care, they trolling around my low skills (it's true, but c'mon, I uploaded it to save it on a site so me and friends could rewatch it sometime...). So I decided I stay on youtube, its good for me.

My problem is that I haven't found any sing how to delete my video. Or can't I? On the biggest WoW movie database users simply can't delete their videos the simple way? :\

I'd like you to delete it.

You can request a deletion via the movie edit page. Its very simple. And I see you have already done it :)
