Okay, there was a screw up and a script seems to have been run twice. And yes, Nefario hasn't been communicative at all, at least not by mail/PM (and I'd be ready to bet he has thousands of emails by now each demanding their money.) And honestly, as soon as GLBSE was closed, I didn't expect much in term of communication with the ensuing flood. At least he's processing payments.
As for shares, I doubt the info will start getting sent before everyone has been paid. Why? You provided a payment address. If issuers knew your address, you wouldn't be able to distinguish between GLBSE's payment and issuer's payments. Which doesn't mean it's not going to be released soon. Hopefully everything will be processed within a few weeks.
Isn't it necessary to fill out some complicated, intrusive forms and submit copies of your ID to someone you barely know in some other country before waiting a few weeks to receive a refund? I'm pretty sure that's how it works.
That requirement was completely removed. You can log in to GLBSE and simply provide an email + BTC address.
As someone else brought up if Nefario had simply stopped deposits and disallowed trading it would have achieved the same result without the issue of double payments. I hope Nefario has some spare btc because I aint covering his screwup.
