They can see your ID number, prefered name, email, OKs and how long you have been a member. No personal information is shared. Not sure that's the case with RS2K....

They actually have a Provider View so you can see exactly what they see:

Client Id:
Preferred Name:    
Location:    
Client Email:
Account Status:  
Active Member For: X Years Y Months Z Days
Membership: Type ( # of Okays )

There's a tab w/ all your OKs

There's another tab w/ your Profile & Bio:
 Does this client like scented lotions and perfumes?
 Clients clothing preference for Providers?
 Does this Client Smoke?
 How does this Client feel about Smoking?
 Clients Preferred Refreshments?
 Clients hobbies and interests?
 Does this Client have Facial Hair?
 Is the Client more than 50 lbs overweight?
 Does the Client have any Health problems?
etc.
 
Not sure how many ladies read the Profile but if they do, they get a nice idea of where you're interests lie

Most independent providers or their assistants read the entire profile, including your write up. Fill it out. It gives them a good idea of what you like. It also helps them decide if you would be compatible. You don't need to be graphic, (it would probably get rejected anyway) just a good outline of your desires. Think of the entire thing as a mini review (yes you wrote it) of yourself. I'm sure a lot of guys lie on it, but I found just being honest and yourself makes for a better experience. Actually I'm more leery of seeing ladies that aren't members. I don't see the downside. Its another great tool like TER that makes hobbying easier. If you are in a smaller market you may want to contact the admin to see if they can give you a rough idea of how many ladies are in your area or sign up for a month (is that an option?) and find out. There are a lot of different ways to hobby, but I've had nothing worse than an average experience with the ladies there. Many excellent ones with more already scheduled.
