Actuall it doesn't, from what I've learned, the second a story turns green it get down rated coz of idiotic people on this site... just saying, that's what happened to most of the others =/

I just want it to look green until I upload my next chapter. Like, if I get 1 rating, then I upload the story so I have 2 chapters, then someone rates it down, it still looks like I have 1 rating... I don't know... Haha. I just really want it. XD xx
