Yeah the prospective client can look at your profile and your reviews/licenses blah blah before they contact you.
They have a "background check" that costs $7 and they put that on your profile as well.
The concept is interesting, and I have gotten a few weekly and BW accounts from there. If you don't submit a quote within about 20 minutes of the job being posted you will probably not even be looked at. So its a waste of $3.33
