As swiftone mentioned the appropriate links above, I will mention something else about the experience system. As you gain experience points, the experience node will also tell you how many points you require to achieve the next level. When you *finally* achieve the vaunted level of Saint, you then are told how many experience points you need to reach that of vroom, who is mostly responsible for this site. As of this post, I need another 997,586 experience points to get there :)
