I would like to point out that most agree that your content is not something of issue, rather your layout/style options are a bit of an issue.
As to elaborate as to what Garret was saying - Most web layouts dont do 100% width of a screen. The main reason for this is readability while it makes it so different screen sizes don't cause a change in the look of the website. This forum, for example, uses a 'scaled' look so to speak (I have no idea what the technical term is hehe)
Also as a rule of thumb, MOST keep all navigation in at least one place (most people seem to put it into two 'panes' - One left for nav, one center (or right) for content. Keep in mind, there is no rules (besides never EVER make a geocities looking site with flash intros and dancing gifs
) to web design, and first in their rubrics mainly grade for content rather than look and 'cool factor' (it can help though)
Also I missed something: on your history page, I like the robot pics but they lack alt tags, and the aliasing on the bots its a little crude, but its my personal opinion.
But im glad you guys decided to resurrect it. Learning web design in this era can be very beneficial.
