I second all of the views so far. I especially agree with what VW has said. I personally used to use Vivastreet, and seen a good few WGs from that site. I haven't once yet seen ant WG on that site that looks anything like their profiles, and many don't deliver what they say on their profiles.
For all of what we know is wrong about AW, IMO it is by far and away the better option than any of the others. I now almost always use AW, and UKP before I decide on which WG that I want to see.
