Please stop naked short-selling in all forms immediately. Naked short-selling allows for blatant manipulation of individual stocks by pools of traders. Thinly traded shares are the most susceptible to this price manipulation.

Also, please encourage your counterparts at the Toronto Stock Exchange to institute similar rules. The use of the broker "Anonymous" has clearly gotten out-of-control.

Thank you,

David Chuhran
