I'll be the first to say, being a newb myself (4 visits); I was scared shitless each and every time. Asking questions, even on the board in of itself can be overwhelming when you see how others get chewed out for asking certain questions. Obviously, this place is a guy's club and you have to be a "member" for any real intel. For general tips you'll find some helpful people. As many have stated, once you've set up your time, and you know how much it is you have to pay for what you're looking for, you're all set. Let them take over, or do your thing.
But god forbid you want to know where to go for an experience with a female that isn't over 60, or whose fake moans don't instantly make you limp; those questions will get you a lashing. Hit up the city and just visit a few places mentioned on the boards; after your first or second experience you'll realize that your mileage will vary GREATLY from the next guy. I think that's half the fun, (if you've got the money to make this a hobby). But definitely don't expect to get the holy grail of information from this or any other site, on where to find the best location, or ladies (if your looking for a one time fling).
