Hey,

I've been wondering this for a while... In the User CP if I look at the "Latest Reputation Received" list, there are green and gray 'gems'. What is the difference? Apparently (according to the file names) the green gems are positive rep, and the gray ones are 'balance' reputation... What does that mean? It can't be negative because there's no option to give a negative rep, right? And often I get a gray gem with a 'thank you' comment behind it so that would not make sense it if was negative...

So what does it do, and how do you give it to someone?
