Today is the last day to move over to a Battle.net account should you wish to continue playing World of Warcarft.
Blizzard has said that it is now a requirement, per Cinemablend, and if you wish to play future titles like Diablo III and StarCraft II, you might as well go ahead and sign up because it is mandatory for those as well.
Battle.net stores all your account information and has a new communication feature and auto opt-in for upcoming Betas.
As a reward for doing so, Blizzard is giving away a free penguin pet:
“If you create a new Battle.net account after November 11 and merge an existing World of Warcraft account with it, you will still be able to receive the pet. However, please note that we plan to remove the ability to get the penguin pet at some point in the future”, said Blizzard.
