Im on 1024 x 768 Mahatma which i believe is pretty much industry standard these days. A lot of sites like Gooners Guide etc still go for the old 800x600 aligned to the left look so as it will always fit on anyone's monitor. I'll get a screen scot of how your site looks on my monitor (we can delete these posts later if you wish, feel free to ask any more info on the Building Your Own Website Thread i started after seeing your thread mahatma)
Thats how it looks when i enter the site and have to click the toolbar to go right to see the main body of text. I would align it to the left mahatma and also i wouldnt go over the 1024px width. Maybe this can tell you more though
