I sent an email to S&S yesterday as I wasn 't sure when my subscription ended. They replied within an hour that it ended the previous month.
I promptly resubscribed on their website. Hopefully the current issue doesn't take too long to get to me.
Great to get a quick response from them but in hindsight I am amazed that they hadn't troubled to at least send me an email to try and get my subscription renewed.
If I hadn't followed it up I don't think anything would have happened.
Should be easy to make use of a database of current subscribers.
