looks good. A few suggestions...
1. Make the original table 700 width, instead of 100%
2. Take the vbulletin banner out and put a button on the menu instead or something.
3. Take the white border around the header image off
4. Since the main table would only be 700 width, center it using the < center> tags
5. Make the left menu a bit smaller to give the middle more room.
... hope those suggestions help. Site looks good though.
