I don't receive e-mail notifications either. I did receive them for the first couple of days I activated the notifications, but now I don't get any. And no, they are not even in the spambox.
Particularly, I would like to get notifications about new posts in the "General Software Discussion", but I don't get them.
Maybe it is me, or maybe it is a general problem, but it seems the notifications do not reach to me.
Have I also told you that I too don't get the notifications?
BTW:
Spoiler
I don't get notifications.
