Karma is a way to show appreciation of another, be it for a good critique, wise advice, or maybe they just made you laugh. You may give karma to others after you have made a minimum of five posts. This is to keep people from making new accounts just to give themselves karma. Who would do that, you ask? Well, we have quite a few karma addicts around here, and there is no telling what they would do for their next fix.
You can also "smite" people, which takes away karma, but we don't do that very often (or do we?
After you reach five posts, you will see two links below each persons screen name, "applaud" and "smite". Applaud gives karma and smite takes it away.
Now I will give you some karma for asking about karma.
