Let me help the poor thing...
Q: What are experience points?
A: Much like in a traditional role playing game, registered users may aquire experience points and gain levels (which are desired for status).
The most notable reason to want experience points is that they add weight to your votes. A user with an abundance of points will have the strength of multiple voters. This means that you can really hurt the movies you hate, and really help the movies you love. We make the assumption that anyone who visits the site daily will have a good idea of what good content is - so frequent visitors have more influence over the rankings! Remember, you must be logged in for your voting power to be augmented!
P.S. The help button should be bigger and in a better place. That would make these topics not nesecary. Maby new users just don´t notice it coz it´s allmost hidden in the top of the site.
