Mail Block: Listener questions and comments

• Question from AWorth: Can the Options House guys explain how their short buyback program works? Is it only for outright shorts, or if I have a short leg of a spread that is near the money on expiration but trading under $.10, can I close that out without commission or do I have to close the whole spread?
• Question from Thomas Hatch: I like dividend yield stocks. I listened to an earlier show and you mentioned writing covered calls to generate dividends. Can I apply this strategy to dividend yield stocks? Any risks I should watch out for when doing this?
