Today we are excited to share with you some news about SharePoint Designer 2007. Starting now (April 2, 2009), SharePoint Designer 2007 will be available as a free download! We want more of you customizing SharePoint and feel that this a good way to put the tool in the hands of more people.Although the heavy lifting still requires Visual Basic, SPD is more helpful to web site designers and publishers. Still the audience is limited by the SharePoint design policy and how many designers will be allowed to make modifications beyond the customizations allowed on the web site.
