Site Tour - Favourite Profiles
You can rate profiles that have details completed (click for larger image).If a member has completed details on their profile (their location, age, gender, race, etc.), then, when you see their profile, you'll see a "Your rating" widget, which will allow you to rate that profile. 
Your favourite profiles are listed along with your rating, the member's thumbnail pic, name, and time of last being on the system (click for a larger image). When you want to go back and see later what profiles you've rated, and what rating you gave them, you just have to choose the "Your Favourites" menu item from the right-side menu, and a list of all your rated profiles will be shown, initially sorted highest rating to lowest rating.
If you decide you want to change or even remove a rating on a user's profile, all you have to do is visit their profile page and change the rating. Simple!
Right now, your ratings are private to you. Not even the member whom you've rated will know. We may change that in future, so you can know who's rated you how. Of course, if you want someone to know you think they're a five-out-of-five, you can always send them a Private Message and tell them.
