Designer should be in tune with WEB 2.0/AJAX Designer must test layout in IE and FF browsers and be familiar with cross browser compatibility. Please provide one link to your best work (web2.0 preferably). This project will be used as ability training test of the designer competence. The initial task will consist in converting an existing site layout (php/html + css + js) into xhtml/css (tableless, must validate W3C).
