I am replying to your answer b/c of the date. I have seen various answers on this subject but many are from 2013 and 2014.
I seem to be having a problem with notifications, a problem that I did not have as of a few days ago. I used to only receive notifications about my own posts. After posting something last night (10/21/15), I suddenly was flooded with email notifications about everything under the sun. I went into my profile and it seems like the email on/off applies to everything. I ended up by turning it OFF and logging out. This afternoon in looking at the email on my iMac I saw that the notifications had indeed stopped. My curiosity brought me back to ASC to see if anyone had responded to my post. One person had but I did not receive an email notification b/c apparently it's all or nothing. Somehow I don't think that can be right. Can you help? Or can anyone who might be reading this help? Please and thank you.
