Yeah, I have it small for people that dont set their resolutions.
I have mine set to 1024x768, but I know a lot of people that dont know the first thing about a computer have it set to 800x600, the default I think. and some people have it set to 600X whatever (400?)
I just dont want anyone to have to scroll to the right to see the site.
However, I have to agree with the others - centre the site (both horizontally and perhaps vertically?).
Also, you may wish to do something with the colour of your links - plain blue is just plain boring! Mabye use a the same green colour (that you used in your image rollovers) on your links' rollover state.
