Tens of thousands of people on the mailing list for BioWare's Old Republic MMO received an email earlier today that basically said "hey, how's that beta treating you?". Even though they weren't in the beta.
Cue an instantaneous freak-out as millions of voices (well, thousands) cried out in terror (well, excitement) and were suddenly silenced, users believing, given the nature of the email, that they'd received a beta invitation and somehow missed it.
So they flooded the game's forums to get more information, to try and find out how to cash in this missing invitation. Which promptly broke the game's forums. Leaving them both excited and confused. Which is never a healthy combination.
If you're reading this, and got one of these emails, and aren't already in the beta: sorry. You weren't invited. You just got an email you weren't supposed to get.
