I did not get an alert for this delicious looking recipe. In fact, now that you mention it, I haven’t gotten an alert (email) for anyone’s recipe posted.
Just received two more notification for this about 15 minutes apart. I had received one 12/20 and commented then as well. I find i get notifications for recipes that are dated from months ago all the time
I took it a step farther and turned my email notifications off in preferences about 3 weeks ago so they'd stop, then I was going to turn it back on thinking it would reset. But I still continue to receive them. Maybe they'll stop when the dates catch up to when I turned it off.
