The US Battle.net FAQ now offers details on how World of Warcraft players will need to start logging in using Battle.net, a few days after this information appeared briefly before disappearing. They say: "After November 11, 2009, you won’t be able to log in to the game unless you merge your account with a Battle.net account." Likewise, the European Battle.net FAQ has the same information with the following date for European players of Blizzard's MMORPG: "After November 12, 2009, you won’t be able to log in to the game unless you merge your account with a Battle.net account." Each FAQ outlines the reasoning behind this requirement as well as how to get your free penguin pet for making the transfer.
