CA details and direction please

I bought this stock on advice of a good friend, and at one stage I should have walked away in front. As I'm sure most are aware, some times what we feel, over rides what we know. Anyway, I'm down a few bucks and would welcome any pathway that might exist to getting some or all of my money back of these wonderful, honest, and trustworthy people. A class action sounds like a fine idea. I would appreciate any direction that would enable a start on this movement.
