Great website! I have almost doubled my number of tutoring clients through Wyzant. Straightforward interface for the most part. My only complaint is the draconian email system-- I often miss emails from students who try to message me from email addresses not associated with their accounts.
Wyzant is also fair with pay. After you've worked about 400 hours (1 year) Wyzant takes a smaller percentage to a point that it really isn't much more that clients I book through Craigslist-- but I get a lot more quality leads. They do a TON of google advertising and yet only take 5-20% of my student's bottom line-- depending on whether they purchased a package or not. 5%? Not much to pay for top rate marketing. Other companies without software based solutions often take 20-80% of what students pay.
