File the lawsuit and announce the law firm. All investors will contact the lawfirm directly.
I suggest you file the lawsuit in a place where they are typically harsher those who mislead and lie to the public. Far away from where the directors live so they are forced to pay for travel and inconvenience them further.
There are rumors of emails and audio/video recordings. Make sure you include David Lucatch and Andrew Osis in the lawsuit. I'm sure all this information will surface in the lawsuit.
