Maybe think about compacting the first page down to a more simple format. The screen opens in a far wider window than shows on the browser and you have to scroll the image to get to another menu. Just overlay the image with you menu and then compact the window so the image is a Background Image. I see your using some piece of software to generate this. Maybe start with base HTML and work up from that. Good idea about the tutorials. Takes a lot of work to maintain a website. I get around 15000-20000 visitors a month but it took ages to get to that level of interest. You just have to create a simple format that people can readily access and that is interesting.
Good idea and well worth the effort. Don`t give up.
