At the time i had access to Cocco, i liked the Photozella pics. But i agree with Pedro, the natural, not so pierced and/or tattood types are my favorites.
And i hope that those Cocco-participants will inspire some other woman, girls, students to join fully naked.
And the last editions of B2B were sponsored by Dutch bank/financial company ING, so may be they could bring in some Dutch progressive flair.
