CWard50 is right about this and I would go a step further on bbw lovers forums.
After a few weeks on the service the only question left was how thin the pool gets outside big cities.
Two of us compared notes on that one and landed in the same place on whether the recommendations improve with use.
Unless you're in a major metro, expect what happens after you flag someone to be the limiting factor on that one.
Whatever you land on, test bbw lovers forums for a week before you judge it.
