It need some spice. the style is way to plain. I guess im the odd ball but the colors dont bother me. but that style is way to bare bones. I can understand simple but wow simple is a serious under statement. I would consider modifying the bingo style by Minor to suit your needs. it comes in multiple colors and the designer will modify the header to suit your needs for a mere fifty bucks.
Anyways i hope i didn't come off harsh. take it for what its worth. its just one mans opinion. lol at least you didn't go hog crazy like i did. simple and clean are not to be found on my forum anywhere.

Anyway good luck with your new endeavor. regardless of the style choice. I love a good pet board.
