The Scroll of Resurrection is a new version of the Recruit-A-Friend program you can use to invite previous subscribers to return to World of Warcraft. Each invitation you email to a friend contains a link to download and try The Burning Crusade for 10 Days FREE. For every friend who returns to the game through your Scroll of Resurrection invitation and then re-subscribes to the game with a paid subscription, you will receive one FREE month of World of Warcraft game time. Click here to visit the Scroll of Resurrection page in Account Management and start resurrecting your friends!
