No that won't. Most brokerage accounts when set up will default to set up as 'cash'. But, to be sure, call your broker and tell them you want your account type as "cash" and also tell them that you do not want your shares to be "borrowed" (ie. shorted). In some cases I have read that it is necessary to say this. I also think that for it to really hold this needs to be done in writing and sent to the firm. (ie. Ameritrade, Etrade, whomever)
Bugzie5 - I urge you to note this on your site to encourage all those share holders to do the same. It may make a difference in the number of shares being shorted!
