First off, here's how to give someone a reputation:
The picture pretty much explains it. Once you click the little green and white plus sign (+), a little green loading sign might pop up at the top of your screen for a second, and then the number in the box next to the plus sign will go up.
You can only give one reputation for each post.
The more reputation you get, the higher the number will be. You can view how much rep you have by...
Go to your profile and scroll down until you see your About Me page. Next to it will show a box with your rep number .
*this part is still in progress*
With your first reputation, your rep status will be neutral.
Once you have ten or more, it will change to good.
Once you get to 20, you get the rank of excellent (thanks Eli2tyree!)
I've been looking around, and it seems that and amount of reputation over 20 is excellent.
Remember to give rep to helpful or nice people, and make sure you don't mix up rep with reporting, that's a whole different story!
It doesn't matter how much reputation you have, but it's always good to be helpful!
