Once any person or group of persons (affiliates and collaborators constitute a group) acquires 5% they have to make a public filing of their ownership interest with the SEC. And other rules kick in if they are acquiring for the purpose or having the effect of changing or influencing the control of the issuer of the securities.
I'm pretty sure the holding/voting day is already set. Back then I had 400,000 U's. It was IMO the real reason we POPPED and dropped before the March court date. I can't remember but I believe it was 3/3/10 at EOD. So unless that changes, it won't matter how much they buy between now and a shareholder's meeting. Fish gets my vote. :-)
