DreamHost, host of this site for the last eleven years, puts out a monthly newsletter, which always ends with unsubscribe instructions. This is the December version:
If the world doesn’t end this month you’ll be on the receiving end of another DreamHost newsletter in January. If it DOES end next month, unsubscribing now would largely just be symbolic. If I were you I’d just let it ride.
Yeah, I can see that.
