200 KB for a 200 x 150 screenshot? That needs optimization - a lot. Oh, it's a 800 x 600 image... still, too large (you can get those below 100 KB easily with a tool like Xat or a similar one) and you should use thumbnails rather than cropping such sizes into a smaller size on the page.
Anyway, the site looks... well, really simple. It's not a very easy-to-use design either, with those blue links on a blue background. Get something more contrasting. I also think that font isn't suited very well for websites, it looks funny but it's not so easy to read after a while. Try to stick to Arial or Verdana, or another common and 'normal' font.
The white background makes it look so much less stylish too.
As for the menu, I'd suggest putting the Home link on top, that's most common and people expect it to be one of the first ones. The forum often comes later. About the forum: that's a lot of boards... does it really need that much boards? My personal experience is that fewer boards make it less cluttered and focus more posts in a single board, making a forum more attractive and easy to use.
About the maps links: when it's a download link, say so. Right now people will expect them to take them to another page with info about the map. It's not a good idea to put downloads directly in the menu.
Oh, and the links section doesn't work. You forgot the http:// part in front of those urls.
And give your page a title, too. I'd say, there's a lot to do there. Good luck with it.
