On Howrse how do you get karma points?

As of 8 February 2012, Howrse has changed the karma system. All players have a maximum of 10 points and players will lose karma for not following the rules. Losing karma means that one will lose privileges on the game such as access to the forums and the ability to private message. Karma can be regained every thirty days after loss of it. New players start with ten points.
