Hey Woody, I modified the image you were using in your signature. Instead of the bright green, I made it transparent. Hopefully it'll look good on both light and dark backgrounds. The original and the larger of the transparent ones -- you will have to click on them to display the full size. Otherwise the images get resized to 350px.
ORIGINAL
TRANSPARENT - 490 x 200
TRANSPARENT - 294 x 120
If you decide to use one of the modified versions, can you serve it from where yours is currently hosted? Thanks. --Dave
