Well, I have to say I've been meaning to ask you the very same question Francesc asked, Ale :) As for me, it is what it says in the box: "ALLOW viewers to rate image" I don't consider it as something done for me (the comments are for me) but for thier freedom of choice. The only ocassions I ban the rating is when I dedicate an image to someone - I just feel that's more 'appropriate' then, don't ask me why... :))) Anyway, whatever the artist's decision about ranking his/her art is, I fully respect it. I too, rank just the images I really like :)))
