No idea, Sam, but whatever it is, I’ve never needed it. Most of this extraneous stuff has no practical purpose, but is added by soft-ware developers to earn their pay. The “bold” & “underline” functions I find useful because they contribute to your intended meaning, but few make use of them.
Right underneath the main list of topic categories you see a list of “unread” topics which shows everything new since you last visited. But if you’re talking about notifications directly to you, that I know nothing about.
My email page is now littered with so much useless garbage of this sort that there’s scarcely space left for the email listings. But it keeps the air-heads amused, no doubt.
