Didn't make the first round of Cataclysm beta invitations? Biting your nails in anticipation for the next round? You can stop biting now. According to blue poster Lylirra, more invites could be going out as soon as this Tuesday or Wednesday:
As with the first round, you don't have to wait for the email -- simply log into your account via either Battle.net or the official World of Warcraft website, go to "Manage My Games" and look for the Cataclysm logo. And again, even if you do seem to receive an official-looking email from Blizzard, don't click the links in the email -- log into your account and verify your beta status that way. Keyloggers and hackers are notorious for taking advantage of players during beta testing periods, so it's better to be safe than sorry.
