Sigma recall for lens issues

I contacted Sigma customer services on sending my lens back in reference to their recall. I just received an Email and the only ones needing to be sent back to them are lens in which the auto focus is not working at all. if it's working you do not need to send it in. That relieved a concern of mine of having it damaged in shipping. I was going to post this in one of the threads that were opened concerning the recall but naturally I failed to find one of the already opened threads.:o
