A suggestion to the forums...
I think that having a search engine in the avatar sction would be nice. For example, if you want a Pikachu as your avatar, instead of browsing trough all the categories, trying to pick which Pikachu looks better (what takes up time and then, after seeing all the categories, you forget where the one you liked most was), you just type "Pikachu" in the engine and the images containig Pikachu as the main character appear.
