I am not sure how others feel, but I would like to express my personal feelings.
I think many, many potential W3T customers are like myself. When I was looking for forum software I found many professional-looking possibilities. However, I felt that ease-of-use was as important as "looks".
My point is that you have an excellent product. But if you want to take a big step towards further success, you need to make W3T as user-friendly as possible. By "user", I mean the Administrator. It needs to be very customizable, easy to manage, and contain as many options as possible.
In your defense, I think W3T comes closer to these features than any other forum software on the market. I hope you continue improving W3T and I, for one, will recommend it to anyone who will listen.
