About two years ago, this A list director known almost as much for the number of women he f**ks as for his directing, decided to keep an electronic journal/blackbook of the woman he had been with, wanted to be with and only heard about. It included their names, reputation, if they were good in bed, if they were bi, if they would have sex to get a role, anything and everything was included. One day he shared his journal with another A list director friend who also has a reputation and that director started adding all of his info as well and where the women overlapped, both reports were included. The two directors decided they wanted to be able to share their information with friends, other directors, and producers and so created an invitation only blog which now has several hundred entries and has been updated as recently as last week. It's like a wiki sex book but these two directors are the only ones who can edit the information or add anything. The only reports that are added are those of the 15 or so people who have access to the site and have had first hand knowledge of the women. No secondhand or rumors are allowed. No actors are allowed access to the site, and no married men either. If one of the 15 gets married or starts living with someone, the password is changed.
