Post it on the blog maybe it'll happen.
I don't think they've been publishing anything for months because if you look at the latest, it says October, and I've submitted 3 ideas, none of which show up under "my ideas"
They give stuff in home for getting a platinum in a specific game. I would like to get cool looking avatars or something to make you stand out for getting a bunch of trophies. But it would be cool also so to see your gamer card get an evolved look for every platinum or level you get, kind of like having your emblem in cod or uncharted change every time you level up. I want some free goddies from the store for getting a platinum.
