How can a skin get when it has just been uploaded and there's 0 download yet ?
1) It's a Master skin. 
2) A 'friendly-rating'. Someone rates it based on who the uploader is. (See quite a lot of those)
3) 'Drive-by' ratings. Some users find it cool to be high on the raters scoreboard, if this still exists, and just go through the galleries and rate everything as high as possible.
I say we make the ratings go all the way to 11.
I say we make the ratings go away....
