AFAIR, all accounts that were compromised have had their password changed and emailed to them.

And, that may be problematical.

I have had two or three different "permanent" e-mail addresses in the past ten years. I once took an ISP up on their offer of "just one address, forever". Six months later they got bought by of one the Baby Bells and suddenly I was no longer mumble@myISP.com but, first mumble@myISP.kwest.com, then mumble@kwest.com, nine months later. And mail to the old addresses were only forwarded for a year.

If the OP is in my bucket, it is entirely possible that the email about the change got dropped into /dev/null somewhere.

I finally hooked up with the ACM's forwarder, so now my permanent address is mumble@acm.org. So long as I remember to update my ACM profile when I move service, my email will always forward to the right address.
