Class action lawsuit. Get everyone together and call some lawyers... Good you didn't invest much.

Eh, lawyers cost way more than I lost, personally, but I'm sure there's going to be plenty of others to pick up some figurative pitchforks. I'm not roughed up about it. Anyone starting any legal action that you're aware of?

Not that I've heard of yet... It's always free to consult a lawer and good ones take a percentage and won't charge you a penny if they don't win. At least accident lawyers work that way.
