In the old forums, I was able to subscribe to a person and get an email notification whenever that person posted something. Doing this may seem like stalking, but I used this to follow a few of my favorite Apple engineers on various teams and found it was a great way to stay up to date with current developments in the topics that interested me. I found a bunch of great topics this way that I would never have seen otherwise.
I’d love it if you could add this feature to the new forums. Thanks!
