How is reputation in UnityAnswers calculated?

Just a curious thought.

=D

+15 points for an accepted answer, +10 for an upvote, -2 for a downvote, -1 for downvoting someone

You can also get +bounty for a bounty question (depending on how much bounty the asker sets)

Most of it is documented in the FAQ: http://answers.unity3d.com/faq
