Hi Vickie,
For the last month or two, all notifications from the Community have gone into my Spam folder, again despite me marking them as "not Spam." Like many it seems, I only get a notification when an editor has responded to a thread, rather than when others have posted on it, despite my choosing to subscribe and receive email notification of new replies...this has never worked for me for posts, other than when the editor has replied.
All the best,
Bob
