I just became aware of something that seems... unfair.
This is the list of all the files I've released.

I think that a member shouldn't be allowed to rate (with stars) or comment on a file if he/she haven't downloaded/purchase it (I think it would be alright to allow them to on the files topic though).
It just makes good sense that "If you haven't purchased the product how can you review it?".
I found it unusual getting rated so low only for the "paid" graphics while the free ones have better ratings.
People rate down just because they don't want to pay for something and I think that isn't fair.

Sorry I guess I missed them, I had a feeling I wouldn't be the first one to post this.
