Aye, I'm not keen on the yellow. I do like the new drop-down menus at the top though ("new" in that if they were there before I somehow never noticed them).
I like the new softer BigSoccer logo and the header and such just the yellow I'm not sure about that yet!
I don't like the yellow. May I recommend silver, such as is found on ussoccer.com? Or blue? Those are my two favorite web background colors. Or slate gray, such as daringfireball.net. And the new Quote and Quick Reply buttons look horribly out of place, like refugees from an entirely different theme. Basically everything is a mess, sort of like the beta screenshots of Windows Vista. Yes, I'm a Mac user.
