Today we opened the Wrath of the Lich King Beta Opt-In program, which gives players a chance to win an invitation to the upcoming Wrath of the Lich King beta. For The Burning Crusade beta, we randomly invited players from the entire World of Warcraft community. With the Opt-In, our goal is to strengthen the beta-testing process by inviting only those players who have expressed active interest in participating. Keep in mind that opting in doesn’t guarantee you’ll be selected for the beta. To opt in to the Wrath of the Lich King beta, visit the Beta Opt-In page. https://www.worldofwarcraft.com/account/beta-opt-in.html
As stated in the blue post, you can reach the Beta Opt-In program at the following URLS.
