From what I can understand, Mark's new attempt to make money is a free directory: girls (or agencies) can advertise without paying. I must say that his WordPress site is pretty well done.
But he also tries to sell advertising space on the site. So far, I see only five or six paid ad. But there is a beginning to everything, is there not?
Good luck Mark, one day you will be able to afford a full meal at MacDonalds earned with your projects on the web!
