Our friends in AdWords have made some improvements for the beta that we think you'll really enjoy! By way of your testing feedback, exit events are no longer required (we'll make the entire ad area clickable by default) and we now accept Google Web Fonts.
We have extended the beta so that new and existing testers can try out the new features. Thanks to all who have already participated and if you have not, sign up now and give it a try! http://goo.gl/n7rF9K
