i guess you are an active myspace member and you are subjected to all the things you are speaking of.
but if you have seen stylish add-on on firefox and the redesigns of many sites on userstyles then you would see what i was speaking of...
anyway, i have made a userstyle for Createdebate... here is a screenshot... this is still in beta... will complete the work soon.
The one reason which is keeping me away from CreateDebate is the white background. I happen to enjoy the debates here and i read all the arguments... but after a long tiring day at work, when i come here to spend sometime.. i just cant read for long because of the background... so please think about the skin option...
