I think I gave you rep, along with almost every other OT member that I've got on my BL...
And, what it does is it makes you a prefered player to that person. If you are only one person's prefered player then your stars will go up or down fast, but if say you have been rated 20 times, having one more prefered player won't change anything.
And just got done with some GRAW with Moistfly.
Sorry I suck
