A fellow webmaster and I have just started a small site for online debating, we think that this is an idea that could perhaps work. We also understand that debating can be done anywhere, but we think that in time we can present a better environment with better tools than any other. Please check out the site, maybe try it out a little. Thanks alot http://everyvote.net/index.php?page=aboutus
I think the colors are too soft, maybe try using a bolder/brighter more saturated green for your header? Some icons would help out the site design a lot as well
