Hello, mate, here is what I have to say to you. Your forum site is like any other forum and if it is not bothering you, than it's not bothering me at all since that is a place where people should change their discussions, views and other stuff, in one word plain forum site. As of your main site, you have a lot of usefull content and that should provide many visitors, which is good, design is not the very top, but it is clean, simple, at hand and I would just make navigation sidebar floating if it is possible since the pages are long. So, goodluck in your future work.
