I would agree with everyone - it very heavy and loads quite slowly. I suggest what you can do is make it simpler at this staeg. Your forum is very targeted, which is good.
But, you have over 20 forums for 6 registered users. I think if you have less forums you can grow much faster. The key to forum success is to attact targeted audience first to the topic - then grow in sections.
Also, its pretty long - it should take me to make 6 scroll-downs to see it all. Can you make it more compact?
Although these are just friendly suggestions.
Good luck with it! Its a good start.
