This notecard explains the ratings system, and how it is important to Second Life.
You are given the option to rate as many people in Second Life as you like. It costs $1 to rate a person, and you have three scales upon which you can weigh them. You can change any or all of the scales, and it will still be $1. It costs $1 so that you think about whether the decision you're about to make is really worth it or not. I mean, let's face it kid, $1 is hard to earn in this tough Second Life! You don't wanna waste that precious dollar on just ANYBODY right?! Here's a review of the scales.
Behavior: Rate a person positive on behavior if you like their attitude. I once rated a person positive just because I liked how much they used the "fart" sound whenever they crouched. If someone farts in your general direction, however, that could warrent a negative rating.
Appearance: Rate a person positive if you like how they look. For instance, you could rate ME positive, because I'm the hottest thang SL has seen since they invented fire (which I hear they did about 2 days into the creation of the game!) Rate everybody else negative, so that I can have the highest rating and be the sexiest avatar on the block.
Building: Rate a person positive in building if you like the objects they create. For instance, you could rate the penis that someone built next to Rivn's house a positive, because let's face it, that's just damn funny! Then you can rate Rivn's house negative, because let's face it, he doesn't even play anymore!

Why is the ratings system important? Well, if a person has high ratings, that person gets more money from the fixed money pool that is held by the Lindens. The ratings basically give the person a specific percentage of that pool. The top rated people are placed on the leaderboard. It's very important to be on the leaderboard. It makes you what the kids call nowadays "leet". I'm not sure what this means though...
Remember that when you look at the leaderboard, you can interpret it any way you like. You may believe these people are the best in their category or just really popular. The reality is they suck. Yeah, I said it, whatcha gonna do about it? Huh?! These people suck at the game!! YOU CAN'T STOP ME FROM TELLING THE TRUTH!! THEY SMELL LIKE DOODOOOOO
Er....
Like I was saying... It's all up to what you decide, how you vote, and the way you live your Second Life.
Keep in mind that the Linden pool of money is divided among every member of the Second Life community, and this knowledge may affect the way you decide to use your votes. It doesn't effect me. I go around and find every person I can and say "Rate me now or I'll bash you into the next century!" as I whip out my enhanced GLOWY SWORD OF DOOM! This should be your first priority as a newbie, to find a huge glowing sword and threaten people to rate you!
Some feel the ratings system is meant to reward those who have advanced their skill at performing tasks in Second Life, some feel it's merely a way to get people to socialize, some just use it as a way to make money. I think the ratings system is something to get off on. Cuz you know.... sometimes I look at my large rating... and I just get soooo turned on. It's like... shooting through the roof it's so large...
Uhhh...
So like I was saying... threaten people to rate you, and make lotsa money! The End! =D
yeah... I think it's perfect!!
