Pretty interesting site. I know Sam has some experience with stuff like this, working on web pages and what not. I honestly am not the most knowledgeable with making banners. I made the one for this site using the basic paint tool on microsoft vista. I would suggest whoever works on it use atleast photoshop or something better.
I will likely get around to changing our banner up here a bit once I get the laptop I have been wanting.
Good luck on getting it pulled together man. Deffinately needs a banner, and certainly is an interesting blogspot.
