It's an address at my own domain. Incoming mail goes to my own server. I searched the mailserver logs and found no other mail for the address, except mail from this board.
But if no one else has received a message about "NEW COURSE: Responsive Web Design - Save $xx", I guess I must have used the address somewhere else.
I would have been very surprised if WebmasterWorld were to blame, as I don't recall any such issue over the past 11 years.
