this is a major problem, and I salute the OP for starting a public conversation.
GLBSE has no support at all which to put it simply: really sucks.
I lost my private key to one of my accounts do to hardware failure back in October and could not retrieve it. Of course this is a learning experience for me and because of it I now backup all my private keys on other medias.
There are several other users who are in the same boat as I am, Nefario stated that he could create another account and move my assets there if I could prove I was me, I can very easily prove I am me of course but since then Nefario has not responded.
I have made several email contacts with no luck.
I think it's the wrong attitude to take to say that if you lose your private keys you are stupid and deserve to lose your account, which is the feeling I have gotten of the course of this problem.
GLBSE needs a ticket system and needs someone who is going to respond to the tickets. I would gladly set up this ticket system and even host it if necessary, but I cannot offer support
Nefario I can completely relate if your time is valuable, I would be happy to even pay you a support fee to be able to get back into my account.
GLBSE needs support, and I really think if Nefario does not have the time to do this he needs to pull one of his trusted friends in that has the time to do this.
I will gladly donate my time and money if at all I can help get something in place and get all of us back into our accounts.
that is all.
