What are Karma points?

As you contribute to the community your profile accumulates Karma points. These points distinguish you as a respected member and one which opinion is highly regarded by the community. Gaining Karma points also opens up doors to some cool features in akaQA which are constantly added.
Here's how karma points work:

* Each "Thumbs Up" on your question or answer yields 15 point.
* Each "Thumbs Down" on your question or answer yields -35 point.
* Each "Thumbs Down" on someone else's question yields -10 points for you for giving the thumbs down.

Number of daily votes

The number of daily votes you can give is limited and grows as you gain more Karma points.

You just started. Answer some questions. Give good valid replies and you will get karma for giving the helpful answers. Begging for karma is not acceptable however ;)
