PB13,, this one is for you. Good starting point on " shorting".

FYI, warrant holders have shorted the stock ( sold it short with intentions of buying it back after the stock is sold down) to cover the costs of exercising the warrants. this is common practice. The large GMP cross today was the beginning of the end for the shorts. Covering is going on as we speak, if not already complete. I do not see a short squeeze taking place on the next leg up since the ones shorting it were the ones in the know, closer to the company than are we.

IMO of course. We are in good hands!
