Regarding IP . . . every site that you visit has that info. It's not possible to avoid it, without looking like a hacker. I know it makes people uncomfortable, so I usually don't mention it. People would absolutely freak out if they knew the sort of info that Walmart or your credit card company have on you! The amount of detail is unbelievable -- your mother literally would not know as much! (I don't have that sort of data, but I've seen examples.)
