ScratchBack is a brand new tipping concept for your blog or website. Whereas traditional Donate buttons are boring the ScratchBack widget is different - it allows publishers to give something back to people leaving a donation. The reward takes the form of a small advertising link or image which is temporarily (depending on the rate of donations) displayed on the publisher's site.
