On April 6th, Wizards of the Coast took all of their PDF products offline, including those sold at third-party websites like RPGNow.com. From the RPGNow front page: 'Wizards of the Coast has instructed us to suspend all sales and downloads of Wizards of the Coast titles. Unfortunately, this includes offering download access to previously purchased Wizards of the Coast titles.' Wizards of the Coast also posted a press release to their website that states they are suing eight file sharers for 'copyright infringement,' and WotC_Trevor posted a short explanation about the cessation of PDF sales to the EN World Forums.
