Hello, please review my Swap and Give out for free website.

Swapond.com

The idea behind it is to create a community that exchanges items or services without using money as a value of exchange. Users can trade multiple items with multiple users. There is a system for evaluating items and users (+ or -) which can create trust. When a user accepts a trade request, the users exchange 'contact cards' (which last 3 days) that contain the contact information that they have selected in the settings.

It is build with Twitter Bootstrap, PHP and JQuery to create a responsive and engaging design.

I am a developer and I am not trained to design. All the graphics and design is done by me, or from stock images, so please be fair.

Any information/comment/suggestion is very welcome.

Thanks in advance,
Anthony.
