Certificate form may not be necessary: I trade online with WebStreet and Datek Online an they both require the shares in my account before I can trade those shares. A margin disable account should prevent your shares from being borrowed by the shorts. Follow this link to see my the communication with Datek. <A HREF="http://www.ragingbull.altavista.com/mboard/boards.cgi?board=GETC&read=301" target="_new">http://www.ragingbull.altavista.com/mboard/boards.cgi?board=GETC&read=301</A> Hope this adds more light.
