Having a NRP is one option, and I totally understand the girls who decide to have a NRP.
I decided against a NRP, and chose instead to become involved on the board. In addition to being my main source of entertainment/procrastination, being an active member here accomplishes two main purposes:
1) It gives potential clients an opportunity to know a little more the person behind the fantasy. Some clients don't care about it, but some do, and I tend to have a better time with the ones who do. Working with an agency, Terb is the only way for me to interact with potential clients before I meet them in person -- although I suspect that many choose to follow Strongbeau's Fight Club rule and not to reveal our previous interaction on Terb, which is perfectly fine by me.
2) By being an active member here, I'm also hoping that clients who choose to write a review will be a little more careful about how they write their review. I don't want to censor the reviewing process nor prevent anyone from writing a critical review -- which is also why I usually don't comment on review threads about me, whether good or bad -- but I do want the reviewer to be mindful that there is a breathing and feeling human being behind the SP he is reviewing.
