Just a little tip for all of you wishing to have a higher level:

Ive discovered a very eazzzzy way to make your percentage go up, each day, write one blog post in your profile, write 2 tags, add 2 persons to your tracked users, add and/or delete 4 games in your game section and write 20 post in forums and your percentage will go up at least by 70%! Its crazy!
