The avatars are cool. Its well hidden, and I'd have to search for it again, but there is a button on one of the many personal options menus that allows you to look at ALL of the avatars at once. It took about ten minutes to load over a cable modem, heaven help those of you with dialups.
My only complaint is that out of the 300,000 avatars, half of them are FREAKIN' POKEMON CHARACTERS!!!
