P411 was always a screening/verification site until a user (or users) requested the ability for ladies to be able to say if they were available now. They used to allow detailed services, but had to remove those due to legal changes in Canada and now it looks like are going to go back to what they initially set out to do - help provide a level of safety for providers and hobby-ists. It isn't perfect but it probably is the best site out there for this.
