AdultFolio is a great site with loads of features that are simple to use making it easy for models/photographers/venues to make contact and coordinate shoots.

I've been using Adultfolio since it's launch.
There is no other site that caters to the world of adult photography the way this does.
The site owner listens to feedback and is always swift to respond so Adultfolio evolves according to the needs of the members.
