In preparation for the launch of these new features, on November 11, 2009, all current World of Warcraft players will be required to merge their World of Warcraft accounts with a Battle.net account in order to log in to the game. As our way to say “thanks” for taking a moment to go through the process, existing World of Warcraft accounts that upgrade to Battle.net (including those that have already switched over) will receive a brand-new penguin in-game pet -- check for him in your in-game mailbox later this week. Starting on November 11, all World of Warcraft players will need to log in to the game using a Battle.net username and password, and anyone who wishes to create a new World of Warcraft account will need to start with a Battle.net account.
Creating a Battle.net account is simple and free. To merge your existing account with a Battle.net account, visit http://us.battle.net . For more info, check out the Battle.net site or read the FAQ: http://us.battle.net/faq/index.html
