On the top left of  the "Reviews" home page is a "Submit a Review" link.  That's where it begins.  Click that, agree to the rules and you get a new window with a mostly blank review form. You are required to fill in Profile Info for each and every review so most people recommend opening the existing Profile in one window and then copying in the info, back and forth, as needed.

IF YOU HAD A DIFFERENT EXPERIENCE OR disagree with the info (real versus fake; CBJ versus BBBJ; blond versus black: girls do dye their hair, put YOUR info into the form. That will help the Admins resolve and Problem Reports, should they come up.

Since there is no place on the blank form for a Profile ID number, some of us recommend beginning the General Details section with something like, "This is a review of Name, TER ID #######. ..."  If it's someone who does not yet have any reviews or Profile, you won't include that, obviously.  And if you're a newbie, you should probably stick with previously reviewed girls anyway.

Fill in the boxes on the form, type up your essays, hit submit and wait for the Admins to look it over.  For someone's FIRST review, it could take a few days.
