I think you're supposed to be active on the forum..by creating and maybe commenting on posts. Please don't create posts about every champion that you get, those type of guys are just annoying.
You get stars by having a certain amount of points on the forums. You can check how many points you have on your forum profile. I can’t remember how many points you need for the lower star ratings but you need 3000 to get 5 stars.
