I did not know this, but Puplava said all shorts must be covered at the time of buyout, both normal and naked. So is not important if you are "lucky" and instead of shares have IOU in your account.
I also believe most of people who bought MFN will not sell that easy and that cheap.
(I have some GRS and I remember my partner saying - they are 37 % up. Sell them, sell them.)
