About the Reviewers Marc Grabanski got involved early on with jQuery by authoring what would become the jQuery UI Datepicker. He works, arguably too much, building user interfaces and web software all the day long with his company MJG International. If I were to thank anyone it would be Jesus Christ for transforming me from a video game addict into something useful to society and the people around me.
