Nice video, that was really professional and original, I don't think many forums have something similar.
I also like the way you have divided up your different forums - that's a really clever way with the top buttons (Community, Business, Monetization etc). But I did not see these buttons at first, so I initially thought your forum only had the Rules and Community sections. You might want to consider making these buttons stand out a bit more.
I like your theme. But it does feel a bit too dark for a business forum - especially if you consider the bright and "happy" design in your promotional video.
Also this: "Business Forums is the home of business men, entrepreneurs, and money making." No business women then?
