Signed up a long long long time ago. To the point where I'm in other invite only betas and completely forgot about this until I received this.
The rest of this email did include a beta key, which they do say lets you continue to advance in the next beta test. However right now it is useless outside of account creation and preloading the game.
Problem I have is, well, according to the email title, The Elder Scrolls Online Beta: Help Us Break the Record!, feels a bit scummy.
I'd be happy to test and provide feedback on your game and my rig free of charge, but not allowing me to play,character create, even login or see login screen news until Friday at noon ?
Notice how the red text points out be there at noon on a weekend is the record requirement.
