So many sections and topic of discussion yet limited content and membership. I recommend you merge sections and began off with just a few. Visitors avert from a forum if it looks empty and inactive. I am speaking from my experience of running multiple forums in the past.
I think you have got the best script for your forums and the best additions and modifications can be seen as well. What you desire is the proper promotion of your forums along with some interesting content on your site. If you are looking to hire some promoter, you can test my services as well. I have around 40+ Satisfied clients already. Please drop a PM if you are interested.
Look/feel - Color is easy on the eyes and not distracting I like it. Easy to navigate Topics - Wow you have a chosen a very broad niche. My sense it will take a long time to get going full speed. All in all I like what you have. Don't know what you had but it looks nice now.
Great website with lots of good information. I like many of the business topics in there, some of which I am using right now
