The banner and colors look great IMHO, but you have always had the problem of stretching too far horizontally on smaller screens. I think I mentioned it to you before that you need to cut down the size of the banner image and replace what you cut out (in the center), with a BG color, create a cell for each image, then left and right justify the other two graphics. With the width set to 100%, the table will stretch or shrink according to resolution.
Now since the tan bar at the bottom is part of the banner, the graphics need to be split and the same thing needs to be done to the bottom separator (the part the says "The Ultimate Online forum..etc.").
Just say the word and I'll fix it.
