Interesting site. I like how you've incorporated the forum into the front page with the "Last Post" mod. The site looks clean and simple.
What I would change:
I would make the forum look more like the rest of the site. Add the menu to the left side. Add the header swoopy image as well.
Also, since you say the forum is just getting noticed, maybe make the "Message Board" link stand out somehow. Maybe with it's own section and sub-menu.
Keep up the good work. It will all pay off.
