nice i find the size of your useful page a tad small maybe? otherwise, on the register page, you should indicate why registering, ie, it's not mandatory but gives more features to the user. and also, i'm not sure your banner under the main square serves a purpose, it stands out too much imho. looks like an ad. maybe you'll put ads there later, ah then ok overall, your site looks great, professional
thanks for the comments, yeah, I am gonna make regestired users have more features, plus I will trade banners. -damien
