Mod,
All I can do is add my two cents from a hobbiest perspective. Cerb works!!!. There will never be a perfect system in place to catch all the undesirables but compared to similar sites on the web, Cerb seems to have all the bases covered. There will always be an element of common sense to be followed by the men. A good general rule of thumb is " if she appears too good to be true then she probably is". ( verify with the Cowboy).
The ladies only section is also very important. Safety is the most important issue for the both MP/ SP's and those who hobby. It is the base on which Cerb is built.
Now on a different note....Mod, Is Cerb hiring? I can't think of a better place to work. You must be thinking of opening an Ottawa office soon. Where should I send my resume? :-D
