I just changed it so that you can see everyone's values. Power is influence, which is based on reputation (1 pt per 100 rep), posts (1 pt per 100 posts), and length of membership (1 pt per year).
I have tons of power because I have tons of posts. If people say I should have better reputaiton, my power to influence others will increase, as well.
