unfortunately the site mentioned in this post is no longer available!
I came across this site www.argue-it.co.uk, its a different way of putting across your point of view. Bascially you have your say, wait for opposition and then debate it.
Its quite a fun way to argue, this is taken from the site:
It’s a place to have your say and make your point. It’s not a forum – it’s one on one debate. Sign up for free, create your argument, wait for opposition and then have fun proving your point. Attract voters to your argument by emailing friends and campaigning other members. Don’t forget to vote on their arguments too.
So sign up and tell them that Maz sent ya.
