That's not bad. Especially since it's excel. But you should change the logo to the old school logo. Seeing as how that was the logo when we won those Super Bowls.

It's basically a cleaned up version of the 1974 dolphin logo with a smaller helmet but with the 1972 look of not going all the way through the sun ring.
No offense, but that Dolphin looks like it is mentally handicapped with the smaller logo. But again, I do like the actual banners. And I am more impressed that you could use it as a sig. That thing looks to bigger than the allowed sizes.
LOL!!! Yeah, it's hard to make a Dolphin, wearing a football helmet, look normal.
I can't remember if I pasted that in or if it's because I'm pointing to a URL. I'll have to redo that and see exactly how I made that happen.
