This morning I found another email from Bioware in my inbox. Was it a beta invite?! No, it was an apology for the previous two emails I'd received, and an assurance that no one had hacked their site.
Anyone who doesn't keep up to date on the forums and/or twitter may not have known why the previous 2 emails were sent, so this is a good communication.
Pity those of us who jump the gun might have seen the email and thought that they were getting a beta invite, eh? :)
