and to answer your question LulzSec hacked the bethesda site and got access to user data, so yes your passwords and emails may have been compromised.

We'll know when a bunch of moreimmature topics begin to overrun various parts of the forums.

That or when a bunch of people come on this site and say that their email was hacked because they used the same password for this forum as their email...

As soon as we have more to share with you guys, we'll let you know
