    This is a problem, indeed. Worse yet, there's only a small chance we can fix
    it anytime soon, seeing as Plastic is currently without either an engineer
    to make a fix or even access to our servers. This inaccessibility, which is
    a long and unsurprisingly stupid story (involving unpaid bills, natch), will
    with any luck improve in the next week, but until then, our choices are bad
    and worse. Bad, in that we have a severe security flaw that can't be fixed
    at the moment. Or worse, that we may have a severe security flaw that
    someone could easily publicize (perhaps this has already happened?), giving
    all idle hands ample time to casually root around through peoples' mail.
    
    I've cc:'d Plastic's ex-engineer, Jon Phelps, in the hopes that he might be
    able to prevail on our long-unpaid (but still hosting!) ISP to give him
    access and patch this up (assuming that he's willing and able.) My fingers
    are tightly crossed.
    
    Any advice on handling this would be welcome in the interim. I'm tempted to
    post it as a story, urging people to delete any sensitive correspondence,
    but again, my fear is that publicizing it without being able to fix it will
    just heighten abuse. And since only a fraction of the people effected would
    likely see the post, there'd be ample time for people to engage in mischief,
    should they be so inclined. Hell, I don't even know whether "deleting"
    messages would actually make them inaccessible. Uggh, I feel ill.
