&gt;Question. Have you had any of your contracts exercised yet? I did once a few weeks ago at 220 and ended up with 5000 shares for about a day which was lucky as it bounced to 225 and i sold. 
  
 if you're selling a put, how can you sell the 'sell put' ?

Are you asking how to close a position when you've sold an option? You buy back the same option (ideally at a lower price than you sold it for). 'Buy to close' is the terminology.
