To get reviewed, you have to see a client that is a member of this site.  If you don't know whether or not he is a member, you will have to ask him.  If he is, you can then ask if he will write a review, assuming of course that he enjoyed his time with you.  You don't have to have a website to get a review, but you do at least need an ad that the reviewer can put on the review.

Hope this helps.

I found a reviewed girl on TER that only had an ad on city vibe, also put an ad on the TER ad board in your area, and post on the message board, this is where the reviewers hang so advertising where we are helps.  I'm in Philly, I love to review, send me a PM, maybe we can hook up
