Subject: File No. S7-24-99 Date: 11/15/99 8:28 AM Dear SEC. I am asking you to control short selling on OTCBB stocks. You must level the playing field.Everyone should be able to trade all stocks equally. In my opinion this is outright market manipulation, and should be against the law in the first place. Thank you for your time and consideration. Mark Zuckerman 9600 Reseda Blvd. Northridge Ca. 91324
