I've activated a Karma feature on this forum. I have never done this till now, as I did not want any negativity to be encouraged. With Twitter and Facebook being so well known, you can now "thumbs-up" a great post, or thank someone who helped you. If a post is not useful or off-topic, you can post a "thumbs-down".
A members overall standing is shown has his or her "karma".
If his feature gets misused, I'll deactivate it again...
