Open Beta Sign-Ups for World of Warcraft!

Here is what Blizzard says:

You can now sign up for the World of Warcraft Open Beta at http://signup.worldofwarcraft.com. Follow the instructions to create your Open Beta account, then begin downloading from the link given at the end of the process (if you have not begun already). Please note that the servers are currently undergoing maintenance in small groups, so the server you wish to play on may not be immediately available. Thank you for your patience, and welcome to World of Warcraft!

UPDATE: Open Beta Sign-Ups for World of Warcraft are closed.
