so..
all you have to do is
Rate the posters video above you, something like (5/5 or 10/10 or whatever you want to..
and while you're at it post a video of your own and so on.
Also it doesn't have to be your own uploads, any random video that you like.
music/trailers/anime/clips/game/ or whatever you think are sweet/cool/etc..
Also it would be better of you to make a comment while you do the rate...
i'll start with this:
